Collectd input data format

Use the collectd input data format to parse collectd binary network protocol data into Telegraf metrics. Tags are created for host, instance, type, and type instance. All collectd values are added as float64 fields.

For more information about the binary network protocol see here.

You can control the cryptographic settings with parser options. Create an authentication file and set collectd_auth_file to the path of the file, then set the desired security level in collectd_security_level.

Additional information including client setup can be found here.

You can also change the path to the typesdb or add additional typesdb using collectd_typesdb.


  service_address = "udp://:25826"

  ## Data format to consume.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  data_format = "collectd"

  ## Authentication file for cryptographic security levels
  collectd_auth_file = "/etc/collectd/auth_file"
  ## One of none (default), sign, or encrypt
  collectd_security_level = "encrypt"
  ## Path of to TypesDB specifications
  collectd_typesdb = ["/usr/share/collectd/types.db"]

  ## Multi-value plugins can be handled two ways.
  ## "split" will parse and store the multi-value plugin data into separate measurements
  ## "join" will parse and store the multi-value plugin as a single multi-value measurement.
  ## "split" is the default behavior for backward compatibility with previous versions of InfluxDB.
  collectd_parse_multivalue = "split"

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
