Python client library

Use the InfluxDB Python client library to integrate InfluxDB into Python scripts and applications.

This guide presumes some familiarity with Python and InfluxDB. If just getting started, see Get started with InfluxDB.

Before you begin

1. Install the InfluxDB Python library:

   pip install influxdb-client
   

2. Visit your InfluxDB URL to ensure InfluxDB is running:

   http://localhost:8086
   

Write data to InfluxDB with Python

We are going to write some data in line protocol using the Python library.

1. In your Python program, import the InfluxDB client library and use it to write data to InfluxDB.

   import influxdb_client
   from influxdb_client.client.write_api import SYNCHRONOUS
   

2. Define a few variables with the name of your bucket, organization, and token.

   bucket = "INFLUX_BUCKET"
   org = "INFLUX_ORG"
   token = "INFLUX_TOKEN"
   url="http://localhost:8086"
   

3. Instantiate the client. The InfluxDBClient object takes three named parameters: url, org, and token. Pass in the named parameters.

   client = influxdb_client.InfluxDBClient(
      url=url,
      token=token,
      org=org
   )
   

   The InfluxDBClient object has a write_api method used for configuration.

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

   write_api = client.write_api(write_options=SYNCHRONOUS)
   

5. Create a point object and write it to InfluxDB using the write method of the API writer object. The write method requires three parameters: bucket, org, and record.

   p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
   write_api.write(bucket=bucket, org=org, record=p)
   

Complete example write script

import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS

bucket = "<my-bucket>"
org = "<my-org>"
token = "<my-token>"
# Store the URL of your InfluxDB instance
url="http://localhost:8086"

client = influxdb_client.InfluxDBClient(
    url=url,
    token=token,
    org=org
)

# Write script
write_api = client.write_api(write_options=SYNCHRONOUS)

p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
write_api.write(bucket=bucket, org=org, record=p)
