collectd

README

Collectd

The collectd format parses the collectd binary network protocol. 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.

Configuration

[[inputs.socket_listener]]
  service_address = "udp://:25826"

  ## Data format to consume.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  ##   https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
  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 compatability with previous versions of influxdb.
  collectd_parse_multivalue = "split"
