InfluxDB Cloud (TSM)

/query 1.x compatibility API

The /query 1.x compatibility endpoint queries InfluxDB Cloud using InfluxQL. Use the GET request method to query data from the /query endpoint.

GET http://localhost:8086/query

The /query compatibility endpoint uses the database and retention policy specified in the query request to map the request to an InfluxDB bucket. For more information, see Database and retention policy mapping.

If you have an existing bucket that doesn’t follow the database/retention-policy naming convention, you must manually create a database and retention policy mapping to query that bucket with the /query compatibility API.

Authentication

Use one of the following authentication methods:

  • token authentication
  • basic authentication with username and password
  • query string authentication with username and password

For more information, see Authentication.

Query string parameters

u

(Optional) The 1.x username to authenticate the request. See query string authentication.

p

(Optional) The 1.x password to authenticate the request. See query string authentication.

db

(Required) The database to query data from. This is mapped to an InfluxDB bucket. See Database and retention policy mapping.

rp

The retention policy to query data from. This is mapped to an InfluxDB bucket. See Database and retention policy mapping.

q

(Required) The InfluxQL query to execute. To execute multiple queries, delimit queries with a semicolon (;).

epoch

Return results with Unix timestamps (also known as epoch timestamps) in the specified precision instead of RFC3339 timestamps with nanosecond precision. The following precisions are available:

  • ns - nanoseconds
  • u or µ - microseconds
  • ms - milliseconds
  • s - seconds
  • m - minutes
  • h - hours

Query examples

Query using basic authentication
