--- title: Get started writing data description: Get started writing data to InfluxDB by learning about line protocol and using tools like Telegraf, client libraries, and the InfluxDB API. url: https://docs.influxdata.com/influxdb3/clustered/get-started/write/ estimated_tokens: 34586 product: InfluxDB Clustered version: clustered --- # Get started writing data - 2 / 3 This tutorial walks you through the fundamental of creating **line protocol** data and writing it to InfluxDB. InfluxDB provides many different options for ingesting or writing data, including the following: - InfluxDB HTTP API (v1 and v2) - Telegraf - `influxctl` CLI - `influx3` data CLI - InfluxDB client libraries If using tools like Telegraf or InfluxDB client libraries, they can build the line protocol for you, but it’s good to understand how line protocol works. ## Line protocol All data written to InfluxDB is written using **line protocol**, a text-based format that lets you provide the necessary information to write a data point to InfluxDB. *This tutorial covers the basics of line protocol, but for detailed information, see the [Line protocol reference](/influxdb3/clustered/reference/syntax/line-protocol/).* ### Line protocol elements Each line of line protocol contains the following elements: \* Required - \* **measurement**: A string that identifies the [table](/influxdb3/clustered/reference/glossary/#table) to store the data in. - **tag set**: Comma-delimited list of key value pairs, each representing a tag. Tag keys and values are unquoted strings. *Spaces, commas, and equal characters must be escaped.* - \* **field set**: Comma-delimited list of key value pairs, each representing a field. Field keys are unquoted strings. *Spaces and commas must be escaped.* Field values can be [strings](/influxdb3/clustered/reference/syntax/line-protocol/#string) (quoted), [floats](/influxdb3/clustered/reference/syntax/line-protocol/#float), [integers](/influxdb3/clustered/reference/syntax/line-protocol/#integer), [unsigned integers](/influxdb3/clustered/reference/syntax/line-protocol/#uinteger), or [booleans](/influxdb3/clustered/reference/syntax/line-protocol/#boolean). - **timestamp**: [Unix timestamp](/influxdb3/clustered/reference/syntax/line-protocol/#unix-timestamp) associated with the data. InfluxDB supports up to nanosecond precision. *If the precision of the timestamp is not in nanoseconds, you must specify the precision when writing the data to InfluxDB.* #### Line protocol element parsing - **measurement**: Everything before the *first unescaped comma before the first whitespace*. - **tag set**: Key-value pairs between the *first unescaped comma* and the *first unescaped whitespace*. - **field set**: Key-value pairs between the *first and second unescaped whitespaces*. - **timestamp**: Integer value after the *second unescaped whitespace*. - Lines are separated by the newline character (`\n`). Line protocol is whitespace sensitive. myMeasurement,tag1=val1,tag2=val2 field1="v1",field2=1i 0000000000000000000 *For schema design recommendations, see [InfluxDB schema design](/influxdb3/clustered/write-data/best-practices/schema-design/).* ## Construct line protocol With a basic understanding of line protocol, you can now construct line protocol and write data to InfluxDB. Consider a use case where you collect data from sensors in your home. Each sensor collects temperature, humidity, and carbon monoxide readings. To collect this data, use the following schema: - **measurement**: `home` - **tags** - `room`: Living Room or Kitchen - **fields** - `temp`: temperature in °C (float) - `hum`: percent humidity (float) - `co`: carbon monoxide in parts per million (integer) - **timestamp**: Unix timestamp in *second* precision The following line protocol sample represents data collected hourly beginning at **2022-01-01T08:00:00Z (UTC)** until **2022-01-01T20:00:00Z (UTC)**. ##### Home sensor data line protocol ```text home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641024000 home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000 home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641027600 home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600 home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641031200 home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200 home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641034800 home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800 home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641038400 home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400 home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641042000 home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000 home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641045600 home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600 home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641049200 home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200 home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641052800 home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800 home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641056400 home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400 home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641060000 home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000 home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641063600 home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600 home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641067200 home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200 ``` ## Write line protocol to InfluxDB The following examples show how to write the preceding [sample data](#home-sensor-data-line-protocol), already in line protocol format, to an InfluxDB Clustered database. To learn more about available tools and options, see [Write data](/influxdb3/clustered/write-data/). Some examples in this getting started tutorial assume your InfluxDB credentials (**URL**, **organization**, and **token**) are provided by [environment variables](/influxdb3/clustered/get-started/setup/?t=InfluxDB+API#configure-authentication-credentials). **influxctl CLI:** Use the [`influxctl write` command](/influxdb3/clustered/reference/cli/influxctl/write/) to write the [home sensor sample data](#home-sensor-data-line-protocol) to your InfluxDB cluster. Provide the following: - Database name using the `--database` flag - Database token using the `--token` flag (use the `INFLUX_TOKEN` environment variable created in [Get started–Set up InfluxDB Clustered](/influxdb3/clustered/get-started/setup/#configure-authentication-credentials)) - Timestamp precision as seconds (`s`) using the `--precision` flag - [Home sensor data line protocol](#home-sensor-data-line-protocol) ```sh influxctl write \ --database get-started \ --token $INFLUX_TOKEN \ --precision s \ 'home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641024000 home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000 home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641027600 home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600 home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641031200 home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200 home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641034800 home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800 home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641038400 home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400 home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641042000 home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000 home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641045600 home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600 home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641049200 home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200 home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641052800 home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800 home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641056400 home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400 home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641060000 home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000 home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641063600 home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600 home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641067200 home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200' ``` If successful, the output is the success message; otherwise, error details and the failure message. **Telegraf:** Use [Telegraf](/telegraf/v1/) to consume line protocol, and then write it to InfluxDB Clustered. 1. If you haven’t already, follow the instructions to [download and install Telegraf](/telegraf/v1/install/). 2. Copy and save the [home sensor data sample](#home-sensor-data-line-protocol) to a file on your local system–for example, `home.lp`. ```sh cat <<- EOF > home.lp home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641024000 home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000 home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641027600 home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600 home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641031200 home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200 home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641034800 home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800 home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641038400 home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400 home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641042000 home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000 home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641045600 home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600 home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641049200 home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200 home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641052800 home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800 home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641056400 home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400 home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641060000 home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000 home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641063600 home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600 home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641067200 home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200 EOF ``` 3. Run the following command to generate a Telegraf configuration file (`telegraf.conf`) that enables the `inputs.file` and `outputs.influxdb_v2` plugins: ```sh mkdir -p iot-project \ && telegraf --sample-config \ --input-filter file \ --output-filter influxdb_v2 \ > iot-project/telegraf.conf ``` 4. In your editor, open `iot-project/telegraf.conf` and configure the following: - **`file` input plugin**: In the `[[inputs.file]].files` list, replace `"/tmp/metrics.out"` with your sample data filename. If Telegraf can’t find a file when started, it stops processing and exits. ```toml [[inputs.file]] ## Files to parse each interval. Accept standard unix glob matching rules, ## as well as ** to match recursive files and directories. files = ["home.lp"] # Set the timestamp precision to the precision in your data. influx_timestamp_precision = '1s' ## Optionally, use the newer, more efficient line protocol parser influx_parser_type = 'upstream' ``` **v1 API:** Write data with your existing workloads that already use the InfluxDB v1 `/write` API endpoint. If migrating data from InfluxDB 1.x, see the [Migrate data from InfluxDB 1.x to InfluxDB InfluxDB Clustered](/influxdb3/clustered/guides/migrate-data/migrate-1x-to-clustered/) guide. To write data to InfluxDB using the [InfluxDB v1 HTTP API](/influxdb3/clustered/reference/api/), send a request to the [InfluxDB API `/write` endpoint](/influxdb3/clustered/api/data-api/write-data/) using the `POST` request method. [POST https://cluster-host.com/write](/influxdb3/clustered/api/data-api/write-data/) Include the following with your request: - **Headers**: - **Authorization**: Bearer - **Content-Type**: text/plain; charset=utf-8 - **Accept**: application/json - **Query parameters**: - **db**: InfluxDB database name - **precision**:[timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) (default is `ns`) - **Request body**: Line protocol as plain text With the InfluxDB Clustered [v1 API `/write` endpoint](/influxdb3/clustered/api/data-api/write-data/), `Authorization: Bearer` and `Authorization: Token` are equivalent and you can use either scheme to pass a database token in your request. Include the word `Bearer` or `Token`, a space, and your **token** value (all case-sensitive). For more information about HTTP API token schemes, see how to [authenticate API requests](/influxdb3/clustered/guides/api-compatibility/v1/). The following example uses cURL and the InfluxDB v1 API to write line protocol to InfluxDB: ```sh response=$(curl --silent --write-out "%{response_code}:-%{errormsg}" \ "https://cluster-host.com/write?db=get-started&precision=s" \ --header "Authorization: Bearer DATABASE_TOKEN" \ --header "Content-type: text/plain; charset=utf-8" \ --header "Accept: application/json" \ --data-binary " home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641024000 home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000 home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641027600 home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600 home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641031200 home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200 home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641034800 home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800 home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641038400 home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400 home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641042000 home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000 home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641045600 home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600 home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641049200 home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200 home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641052800 home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800 home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641056400 home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400 home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641060000 home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000 home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641063600 home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600 home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641067200 home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200 ") # Format the response code and error message output. response_code=${response%%:-*} errormsg=${response#*:-} # Remove leading and trailing whitespace from errormsg errormsg=$(echo "${errormsg}" | tr -d '[:space:]') echo "$response_code" if [[ $errormsg ]]; then echo "$errormsg" fi ``` Replace the following: - `DATABASE_TOKEN`: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with sufficient permissions to the specified database If successful, the output is an HTTP `204 No Content` status code; otherwise, the error status code and failure message. ``` 204 ``` **v2 API:** To write data to InfluxDB using the [InfluxDB v2 HTTP API](/influxdb3/clustered/reference/api/), send a request to the InfluxDB API `/api/v2/write` endpoint using the `POST` request method. [POST https://cluster-host.com/api/v2/write](/influxdb3/clustered/api/data-api/write-data/) Include the following with your request: - **Headers**: - **Authorization**: Bearer - **Content-Type**: text/plain; charset=utf-8 - **Accept**: application/json - **Query parameters**: - **bucket**: InfluxDB database name - **precision**:[timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) (default is `ns`) - **Request body**: Line protocol as plain text The InfluxDB Clustered v2 API `/api/v2/write` endpoint supports `Bearer` and `Token` authorization schemes and you can use either scheme to pass a database token in your request. For more information about HTTP API token schemes, see how to [authenticate API requests](/influxdb3/clustered/guides/api-compatibility/v2/).

The following steps include setting up a Python virtual environment to scope dependencies to your current project. 1. Create a module directory and navigate into it–for example: ```bash mkdir -p influxdb_py_client && cd influxdb_py_client ``` 2. Setup your Python virtual environment. Inside of your module directory, enter the following command: ```bash python -m venv envs/virtual-env ``` 3. Activate the virtual environment. ```bash source ./envs/virtual-env/bin/activate ``` 4. Install the client library package: ```bash pip install influxdb3-python ``` The `influxdb3-python` package provides the `influxdb_client_3` module and also installs the [`pyarrow` package](https://arrow.apache.org/docs/python/index.html) for working with Arrow data returned from queries. 5. In your terminal or editor, create a new file for your code–for example: `write.py`. ```bash touch write.py ``` 6. Inside of `write.py`, enter the following sample code: ```py from influxdb_client_3 import InfluxDBClient3 import os # INFLUX_TOKEN is an environment variable you assigned to your # database WRITE token value. token = os.getenv('INFLUX_TOKEN') # host is the URL hostname without protocol or trailing slash client = InfluxDBClient3( host='cluster-host.com', org='', token=token, database='get-started' ) lines = [ "home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641024000", "home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000", "home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641027600", "home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600", "home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641031200", "home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200", "home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641034800", "home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800", "home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641038400", "home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400", "home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641042000", "home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000", "home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641045600", "home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600", "home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641049200", "home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200", "home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641052800", "home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800", "home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641056400", "home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400", "home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641060000", "home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000", "home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641063600", "home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600", "home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641067200", "home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200" ] client.write(lines,write_precision='s') ``` The sample does the following: 1. Imports the `InfluxDBClient3` object from the `influxdb_client_3` module. 2. Calls the `InfluxDBClient3()` constructor to instantiate an InfluxDB client configured with the following credentials: - **`host`**: InfluxDB cluster hostname (URL without protocol or trailing slash) - **`org`**: an empty or arbitrary string (InfluxDB ignores this parameter) - **`token`**: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with write access to the specified database. *Store this in a secret store or environment variable to avoid exposing the raw token string.* - **`database`**: the name of the InfluxDB Clustered database to write to 3. Defines a list of line protocol strings where each string represents a data record. 4. Calls the `client.write()` method with the line protocol record list and write options. **Because the timestamps in the sample line protocol are in second precision, the example passes the `write_precision='s'` option to set the [timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) to seconds.** 7. To execute the module and write line protocol to your InfluxDB Clustered database, enter the following command in your terminal: ```bash python write.py ``` If successful, the output is the success message; otherwise, error details and the failure message. **Go:** To write data to InfluxDB Clustered using Go, use the InfluxDB 3 [influxdb3-go client library package](https://github.com/InfluxCommunity/influxdb3-go). 1. Inside of your project directory, create a new module directory and navigate into it. ```bash mkdir -p influxdb_go_client && cd influxdb_go_client ``` 2. Initialize a new Go module in the directory. ```bash go mod init influxdb_go_client ``` 3. In your terminal or editor, create a new file for your code–for example: `write.go`. ```bash touch write.go ``` 4. Inside of `write.go`, enter the following sample code: ```go package main import ( "context" "os" "fmt" "log" "github.com/InfluxCommunity/influxdb3-go/v2/influxdb3" ) // Write line protocol data to InfluxDB func WriteLineProtocol() error { // INFLUX_TOKEN is an environment variable you assigned to your // database WRITE token value. token := os.Getenv("INFLUX_TOKEN") database := os.Getenv("INFLUX_DATABASE") // Initialize a client with URL and token, // and set the timestamp precision for writes. client, err := influxdb3.New(influxdb3.ClientConfig{ Host: "https://cluster-host.com", Token: token, Database: database, WriteOptions: &influxdb3.WriteOptions{Precision: lineprotocol.Second}, }) // Close the client when the function returns. defer func(client *influxdb3.Client) { err := client.Close() if err != nil { panic(err) } }(client) // Define line protocol records to write. // Use a raw string literal (denoted by backticks) // to preserve backslashes and prevent interpretation // of escape sequences--for example, escaped spaces in tag values. lines := [...]string{ `home,room=Living\ Room temp=21.1,hum=35.9,co=0i 1641124000`, `home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641124000`, `home,room=Living\ Room temp=21.4,hum=35.9,co=0i 1641127600`, `home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641127600`, `home,room=Living\ Room temp=21.8,hum=36.0,co=0i 1641131200`, `home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641131200`, `home,room=Living\ Room temp=22.2,hum=36.0,co=0i 1641134800`, `home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641134800`, `home,room=Living\ Room temp=22.2,hum=35.9,co=0i 1641138400`, `home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641138400`, `home,room=Living\ Room temp=22.4,hum=36.0,co=0i 1641142000`, `home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641142000`, `home,room=Living\ Room temp=22.3,hum=36.1,co=0i 1641145600`, `home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641145600`, `home,room=Living\ Room temp=22.3,hum=36.1,co=1i 1641149200`, `home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641149200`, `home,room=Living\ Room temp=22.4,hum=36.0,co=4i 1641152800`, `home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641152800`, `home,room=Living\ Room temp=22.6,hum=35.9,co=5i 1641156400`, `home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641156400`, `home,room=Living\ Room temp=22.8,hum=36.2,co=9i 1641160000`, `home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641160000`, `home,room=Living\ Room temp=22.5,hum=36.3,co=14i 1641163600`, `home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641163600`, `home,room=Living\ Room temp=22.2,hum=36.4,co=17i 1641167200`, `home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641167200`, } // Iterate over the lines array and write each line // separately to InfluxDB for _, record := range lines { err = client.Write(context.Background(), []byte(record)) if err != nil { log.Fatalf("Error writing line protocol: %v", err) } } if err != nil { panic(err) } fmt.Println("Data has been written successfully.") return nil } ``` The sample does the following: 1. Imports required packages. 2. Defines a `WriteLineProtocol()` function that does the following: 1. To instantiate the client, calls the `influxdb3.New(influxdb3.ClientConfig)` function and passes the following: - **`Host`**: the InfluxDB cluster URL - **`Database`**: The name of your InfluxDB Clustered database - **`Token`**: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with *write* access to the specified database. *Store this in a secret store or environment variable to avoid exposing the raw token string.* - **`WriteOptions`**: `influxdb3.WriteOptions` options for writing to InfluxDB. **Because the timestamps in the sample line protocol are in second precision, the example passes the `Precision: lineprotocol.Second` option to set the [timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) to seconds.** 2. Defines a deferred function that closes the client when the function returns. 3. Defines an array of line protocol strings where each string represents a data record. 4. Iterates through the array of line protocol and calls the write client’s `Write()` method to write each line of line protocol separately to InfluxDB. 5. In your editor, create a `main.go` file and enter the following sample code that calls the `WriteLineProtocol()` function: ```go package main // Module main function func main() { WriteLineProtocol() } ``` 6. To install dependencies and write the data to your InfluxDB Clustered database, enter the following command into your terminal: ```sh go mod tidy && go run influxdb_go_client ``` If successful, the output is the success message; otherwise, error details and the failure message. **Node.js:** 1. If you haven’t already, follow the instructions for [Downloading and installing Node.js and npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) for your system. 2. In your terminal, enter the following command to create a `influxdb_js_client` directory for your project: ```bash mkdir influxdb_js_client && cd influxdb_js_client ``` 3. Inside of `influxdb_js_client`, enter the following command to initialize a package. This example configures the package to use [ECMAScript modules (ESM)](https://nodejs.org/api/packages.html#modules-loaders). ```bash npm init -y; npm pkg set type="module" ``` 4. Install the `@influxdata/influxdb3-client` JavaScript client library as a dependency to your project. ```bash npm install --save @influxdata/influxdb3-client ``` 5. In your terminal or editor, create a `write.js` file. ```bash touch write.js ``` 6. Inside of `write.js`, enter the following sample code: ```js // write.js import { InfluxDBClient } from '@influxdata/influxdb3-client'; /** * Set InfluxDB credentials. */ const host = 'cluster-host.com'; const database = 'get-started'; /** * INFLUX_TOKEN is an environment variable you assigned to your * WRITE token value. */ const token = process.env.INFLUX_TOKEN; /** * Write line protocol to InfluxDB using the JavaScript client library. */ export async function writeLineProtocol() { /** * Instantiate an InfluxDBClient */ const client = new InfluxDBClient({ host, token }); /** * Define line protocol records to write. */ const records = [ `home,room=Living\\ Room temp=21.1,hum=35.9,co=0i 1641124000`, `home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641124000`, `home,room=Living\\ Room temp=21.4,hum=35.9,co=0i 1641127600`, `home,room=Kitchen temp=23.0,hum=36.2,co=0 1641127600`, `home,room=Living\\ Room temp=21.8,hum=36.0,co=0i 1641131200`, `home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641131200`, `home,room=Living\\ Room temp=22.2,hum=36.0,co=0i 1641134800`, `home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641134800`, `home,room=Living\\ Room temp=22.2,hum=35.9,co=0i 1641138400`, `home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641138400`, `home,room=Living\\ Room temp=22.4,hum=36.0,co=0i 1641142000`, `home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641142000`, `home,room=Living\\ Room temp=22.3,hum=36.1,co=0i 1641145600`, `home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641145600`, `home,room=Living\\ Room temp=22.3,hum=36.1,co=1i 1641149200`, `home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641149200`, `home,room=Living\\ Room temp=22.4,hum=36.0,co=4i 1641152800`, `home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641152800`, `home,room=Living\\ Room temp=22.6,hum=35.9,co=5i 1641156400`, `home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641156400`, `home,room=Living\\ Room temp=22.8,hum=36.2,co=9i 1641160000`, `home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641160000`, `home,room=Living\\ Room temp=22.5,hum=36.3,co=14i 1641163600`, `home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641163600`, `home,room=Living\\ Room temp=22.2,hum=36.4,co=17i 1641167200`, `home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641167200`, ]; /** * Creates an array that contains separate write request promises * for all the records. */ const writePromises = records.map((record) => { return client.write(record, database, '', { precision: 's' }).then( () => `Data has been written successfully: ${record}`, () => `Failed writing data: ${record}` ); }); /** * Wait for all the write promises to settle, and then output the results. */ const writeResults = await Promise.allSettled(writePromises); writeResults.forEach((write) => console.log(write.value)); /** Close the client to release resources. */ await client.close(); } ``` The sample code does the following: 1. Imports the `InfluxDBClient` class. 2. Calls the `new InfluxDBClient()` constructor and passes a `ClientOptions` object to instantiate a client configured with InfluxDB credentials. - **`host`**: your InfluxDB cluster URL - **`token`**: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with *write* access to the specified database. *Store this in a secret store or environment variable to avoid exposing the raw token string.* 3. Defines a list of line protocol strings where each string represents a data record. 4. Calls the client’s `write()` method for each record, defines the success or failure message to return, and collects the pending promises into the `writePromises` array. Each call to `write()` passes the following arguments: - **`record`**: the line protocol record - **`database`**: the name of the InfluxDB Clustered database to write to - **`{precision}`**: a `WriteOptions` object that sets the `precision` value. **Because the timestamps in the sample line protocol are in second precision, the example passes `s` as the `precision` value to set the write [timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) to seconds.** 5. Calls `Promise.allSettled()` with the promises array to pause execution until the promises have completed, and then assigns the array containing success and failure messages to a `writeResults` constant. 6. Iterates over and prints the messages in `writeResults`. 7. Closes the client to release resources. 7. In your terminal or editor, create an `index.js` file. 8. Inside of `index.js`, enter the following sample code to import and call `writeLineProtocol()`: ```js // index.js import { writeLineProtocol } from './write.js'; /** * Execute the client functions. */ async function main() { /** Write line protocol data to InfluxDB. */ await writeLineProtocol(); } main(); ``` 9. In your terminal, execute `index.js` to write to InfluxDB Clustered: ```sh node index.js ``` If successful, the output is the success message; otherwise, error details and the failure message. **C#:** 1. If you haven’t already, follow the [Microsoft.com download instructions](https://dotnet.microsoft.com/en-us/download) to install .NET and the `dotnet` CLI. 2. In your terminal, create an executable C# project using the .NET **console** template. ```sh dotnet new console --name influxdb_csharp_client ``` 3. Change into the generated `influxdb_csharp_client` directory. ```sh cd influxdb_csharp_client ``` 4. Run the following command to install the latest version of the InfluxDB 3 C# client library. ```sh dotnet add package InfluxDB3.Client ``` 5. In your editor, create a `Write.cs` file and enter the following sample code: ```c# // Write.cs using System; using System.Threading.Tasks; using InfluxDB3.Client; using InfluxDB3.Client.Query; namespace InfluxDBv3; public class Write { /** * Writes line protocol to InfluxDB using the C# .NET client * library. */ public static async Task WriteLines() { // Set InfluxDB credentials const string host = "https://cluster-host.com"; string? database = "get-started"; /** * INFLUX_TOKEN is an environment variable you assigned to your * WRITE token value. */ string? token = System.Environment .GetEnvironmentVariable("INFLUX_TOKEN"); // Instantiate the InfluxDB client with credentials. using var client = new InfluxDBClient( host, token: token, database: database); /** * Define an array of line protocol strings to write. * Include an additional backslash to preserve backslashes * and prevent interpretation of escape sequences---for example, * escaped spaces in tag values. */ string[] lines = new string[] { "home,room=Living\\ Room temp=21.1,hum=35.9,co=0i 1641024000", "home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000", "home,room=Living\\ Room temp=21.4,hum=35.9,co=0i 1641027600", "home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600", "home,room=Living\\ Room temp=21.8,hum=36.0,co=0i 1641031200", "home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200", "home,room=Living\\ Room temp=22.2,hum=36.0,co=0i 1641034800", "home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800", "home,room=Living\\ Room temp=22.2,hum=35.9,co=0i 1641038400", "home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400", "home,room=Living\\ Room temp=22.4,hum=36.0,co=0i 1641042000", "home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000", "home,room=Living\\ Room temp=22.3,hum=36.1,co=0i 1641045600", "home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600", "home,room=Living\\ Room temp=22.3,hum=36.1,co=1i 1641049200", "home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200", "home,room=Living\\ Room temp=22.4,hum=36.0,co=4i 1641052800", "home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800", "home,room=Living\\ Room temp=22.6,hum=35.9,co=5i 1641056400", "home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400", "home,room=Living\\ Room temp=22.8,hum=36.2,co=9i 1641060000", "home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000", "home,room=Living\\ Room temp=22.5,hum=36.3,co=14i 1641063600", "home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600", "home,room=Living\\ Room temp=22.2,hum=36.4,co=17i 1641067200", "home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200" }; // Write each record separately. foreach (string line in lines) { // Write the record to InfluxDB with timestamp precision in seconds. await client.WriteRecordAsync( record: line, precision: WritePrecision.S); Console.WriteLine( "Data has been written successfully: {0,-30}", line); } } } ``` The sample does the following: 1. Calls the `new InfluxDBClient()` constructor to instantiate a client configured with InfluxDB credentials. - **`host`**: your InfluxDB cluster URL - **`database`**: the name of the InfluxDB Clustered database to write to - **`token`**: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with *write* access to the specified database. *Store this in a secret store or environment variable to avoid exposing the raw token string.* *The `using` statement ensures that the program disposes of the client when it’s no longer needed.* 2. Defines an array of line protocol strings where each string represents a data record. 3. Calls the client’s `WriteRecordAsync()` method to write each line protocol record to InfluxDB. **Because the timestamps in the sample line protocol are in second precision, the example passes the [`WritePrecision.S` enum value](https://github.com/InfluxCommunity/influxdb3-csharp/blob/main/Client/Write/WritePrecision.cs) to the `precision:` option to set the[timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) to seconds.** 6. In your editor, open the `Program.cs` file and replace its contents with the following: ```c# // Program.cs using System; using System.Threading.Tasks; namespace InfluxDBv3; public class Program { public static async Task Main() { await Write.WriteLineProtocol(); } } ``` The `Program` class shares the same `InfluxDBv3` namespace as the `Write` class you defined in the preceding step and defines a `Main()` function that calls `Write.WriteLineProtocol()`. The `dotnet` CLI recognizes `Program.Main()` as the entry point for your program. 7. To build and execute the program and write the line protocol to your InfluxDB Clustered database, enter the following command in your terminal: ```sh dotnet run ``` If successful, the output is the success message; otherwise, error details and the failure message. **Java:** *The tutorial assumes using Maven version 3.9 and Java version >= 15.* 1. If you haven’t already, follow the instructions to download and install the [Java JDK](https://www.oracle.com/java/technologies/downloads/) and [Maven](https://maven.apache.org/download.cgi) for your system. 2. In your terminal or editor, use Maven to generate a project–for example: ```bash mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate \ -DarchetypeArtifactId="maven-archetype-quickstart" \ -DarchetypeGroupId="org.apache.maven.archetypes" -DarchetypeVersion="1.4" \ -DgroupId="com.influxdbv3" -DartifactId="influxdb_java_client" -Dversion="1.0" ``` Maven creates the `` directory (`./influxdb_java_client`) that contains a `pom.xml` and scaffolding for your `com.influxdbv3.influxdb_java_client` Java application. 3. In your terminal or editor, change into the `./influxdb_java_client` directory–for example: ```bash cd ./influxdb_java_client ``` 4. In your editor, open the `pom.xml` Maven configuration file and add the `com.influxdb.influxdb3-java` client library into `dependencies`. ```pom ... ... com.influxdb influxdb3-java 0.1.0 ... ``` 5. To check your `pom.xml` for problems, run Maven’s `validate` command–for example, enter the following in your terminal: ```bash mvn validate ``` 6. In your editor, navigate to the `./influxdb_java_client/src/main/java/com/influxdbv3` directory and create a `Write.java` file. 7. In `Write.java`, enter the following sample code: ```java // Write.java package com.influxdbv3; import java.util.List; import com.influxdb.v3.client.InfluxDBClient; import com.influxdb.v3.client.write.WriteOptions; import com.influxdb.v3.client.write.WritePrecision; /** * Writes line protocol to InfluxDB using the Java client * library. */ public final class Write { /** * Write data to InfluxDB 3. */ private Write() { //not called } /** * @throws Exception */ public static void writeLineProtocol() throws Exception { // Set InfluxDB credentials final String host = "https://cluster-host.com"; final String database = "get-started"; /** * INFLUX_TOKEN is an environment variable you assigned to your * WRITE token value. */ final char[] token = (System.getenv("INFLUX_TOKEN")). toCharArray(); // Instantiate the InfluxDB client. try (InfluxDBClient client = InfluxDBClient.getInstance(host, token, database)) { // Create a list of line protocol records. final List records = List.of( "home,room=Living\\ Room temp=21.1,hum=35.9,co=0i 1641024000", "home,room=Kitchen temp=21.0,hum=35.9,co=0i 1641024000", "home,room=Living\\ Room temp=21.4,hum=35.9,co=0i 1641027600", "home,room=Kitchen temp=23.0,hum=36.2,co=0i 1641027600", "home,room=Living\\ Room temp=21.8,hum=36.0,co=0i 1641031200", "home,room=Kitchen temp=22.7,hum=36.1,co=0i 1641031200", "home,room=Living\\ Room temp=22.2,hum=36.0,co=0i 1641034800", "home,room=Kitchen temp=22.4,hum=36.0,co=0i 1641034800", "home,room=Living\\ Room temp=22.2,hum=35.9,co=0i 1641038400", "home,room=Kitchen temp=22.5,hum=36.0,co=0i 1641038400", "home,room=Living\\ Room temp=22.4,hum=36.0,co=0i 1641042000", "home,room=Kitchen temp=22.8,hum=36.5,co=1i 1641042000", "home,room=Living\\ Room temp=22.3,hum=36.1,co=0i 1641045600", "home,room=Kitchen temp=22.8,hum=36.3,co=1i 1641045600", "home,room=Living\\ Room temp=22.3,hum=36.1,co=1i 1641049200", "home,room=Kitchen temp=22.7,hum=36.2,co=3i 1641049200", "home,room=Living\\ Room temp=22.4,hum=36.0,co=4i 1641052800", "home,room=Kitchen temp=22.4,hum=36.0,co=7i 1641052800", "home,room=Living\\ Room temp=22.6,hum=35.9,co=5i 1641056400", "home,room=Kitchen temp=22.7,hum=36.0,co=9i 1641056400", "home,room=Living\\ Room temp=22.8,hum=36.2,co=9i 1641060000", "home,room=Kitchen temp=23.3,hum=36.9,co=18i 1641060000", "home,room=Living\\ Room temp=22.5,hum=36.3,co=14i 1641063600", "home,room=Kitchen temp=23.1,hum=36.6,co=22i 1641063600", "home,room=Living\\ Room temp=22.2,hum=36.4,co=17i 1641067200", "home,room=Kitchen temp=22.7,hum=36.5,co=26i 1641067200" ); /** * Write each record separately to InfluxDB with timestamp * precision in seconds. * If no error occurs, print a success message. * */ for (String record : records) { client.writeRecord(record, new WriteOptions(null, null, WritePrecision.S)); System.out.printf("Data has been written successfully: %s%n", record); } } } } ``` The sample code does the following: 1. Imports the following classes: - `java.util.List`; - `com.influxdb.v3.client.InfluxDBClient` - `com.influxdb.v3.client.write.WriteParameters` - `com.influxdb.v3.client.write.WritePrecision` 2. Calls `InfluxDBClient.getInstance()` to instantiate a client configured with InfluxDB credentials. - **`host`**: your InfluxDB cluster URL - **`database`**: the name of the InfluxDB Clustered database to write to - **`token`**: a [database token](/influxdb3/clustered/admin/tokens/#database-tokens) with *write* access to the specified database. *Store this in a secret store or environment variable to avoid exposing the raw token string.* 3. Defines a list of line protocol strings where each string represents a data record. 4. Calls the client’s `writeRecord()` method to write each record separately to InfluxDB. **Because the timestamps in the sample line protocol are in second precision, the example passes the [`WritePrecision.S` enum value](https://github.com/InfluxCommunity/influxdb3-java/blob/main/src/main/java/com/influxdb/v3/client/write/WritePrecision.java) as the `precision` argument to set the write [timestamp precision](/influxdb3/clustered/reference/glossary/#timestamp-precision) to seconds.** 8. In your editor, open the `App.java` file (created by Maven) and replace its contents with the following sample code: ```java // App.java package com.influxdbv3; /** * Execute the client functions. * */ public class App { /** * @param args * @throws Exception */ public static void main(final String[] args) throws Exception { // Write data to InfluxDB 3. Write.writeLineProtocol(); } } ``` - The `App` class and `Write` class are part of the same `com.influxdbv3` package (your project **groupId**). - `App` defines a `main()` function that calls `Write.writeLineProtocol()`. 9. In your terminal or editor, use Maven to install dependencies and compile the project code–for example: ```bash mvn compile ``` 10. In your terminal or editor, execute `App.main()` to write to InfluxDB–for example, using Maven: ```sh mvn exec:java -Dexec.mainClass="com.influxdbv3.App" ``` If successful, the output is the success message; otherwise, error details and the failure message.
