InfluxDB client libraries

InfluxDB v2 client libraries are language-specific packages that integrate with the InfluxDB v2 API and support both InfluxDB 1.8+ and InfluxDB 2.x.

Client libraries

Functionality varies between client libraries. Refer to client libraries on GitHub for specifics regarding each client library.

Install and use a client library

To install and use the Python client library, follow the instructions below. To install and use other client libraries, refer to the client library documentation for detail.

Install and use the Python client library

1. Install the Python client library.

   pip install influxdb-client
   

   • Copy
   • Fill window

2. Ensure that InfluxDB is running. If running InfluxDB locally, visit http://localhost:8086. (If using InfluxDB Cloud, visit the URL of your InfluxDB Cloud UI.)

3. In your program, import the client library and use it to write data to InfluxDB. For example:

   import influxdb_client
   from influxdb_client.client.write_api import SYNCHRONOUS
   

   • Copy
   • Fill window

4. Define your database and token variables, and create a client and writer object. The InfluxDBClient object takes 2 parameters: url and token

   database = "<my-db>"
   token = "<my-token>"
   client = influxdb_client.InfluxDBClient(
   url="http://localhost:8086",
   token=token,
   

   Change InfluxDB URL

   • Copy
   • Fill window

   The database (and retention policy, if applicable) are converted to a bucket data store compatible with InfluxDB v2.

5. Instantiate a writer object using the client object and the write_api method. Use the write_api method to configure the writer object.

   client = influxdb_client.InfluxDBClient(url=url, token=token)
   write_api = client.write_api(write_options=SYNCHRONOUS)
   

   • Copy
   • Fill window

6. Create a point object and write it to InfluxDB using the write method of the API writer object. The write method requires three parameters: database, (optional) retention policy, and record.

   p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
   write_api.write(database:rp, record=p)
