InfluxDB Clustered

influxctl write

  • influxctl 2.4.0+

The influxctl write command writes line protocol to InfluxDB Clustered.

Provide line protocol in one of the following ways:

  • a string on the command line
  • a path to a file that contains line protocol
  • a single dash (-) to read line protocol from stdin

Important to note

  • This command supports only one write request per execution, but does support multiple lines of line protocol and will batch data based on the --batch-size.
  • This command is not meant to be a full, feature-rich write tool. It’s meant for debug, triage, and initial exploration.

InfluxDB connection configuration

Your InfluxDB cluster host and port are configured in your in your influxctl connection profile. Default uses TLS and port 443. You can set a default database and token to use for the query and write commands in your connection profile or pass them with the command using the --database and --token flags. Command line flags override settings in the connection profile.

Usage

influxctl write [flags] <LINE_PROTOCOL>

Arguments

ArgumentDescription
LINE_PROTOCOLLine protocol to write (command line string, path to file, or - to read from stdin)

Flags

FlagDescription
--batch-sizeNumber of metrics to write per batch (default is 10000)
--databaseDatabase to write to
--precisionPrecision of data timestamps (ns (default), us, ms, or s)
--timeoutClient timeout in seconds (default is 10)
--tokenDatabase token with write permissions on the target database
-h--helpOutput command help

Also see influxctl global flags.

Examples

In the examples below, replace the following:

  • DATABASE_TOKEN: Database token with write access to the target database
  • DATABASE_NAME: Name of the database to write to
