collectdedit

Read events from the collectd binary protocol over the network via udp. See https://collectd.org/wiki/index.php/Binary_protocol

Configuration in your Logstash configuration file can be as simple as:

input {
  udp {
    port => 25826
    buffer_size => 1452
    codec => collectd { }
  }
}

A sample collectd.conf to send to Logstash might be:

Hostname    "host.example.com"
LoadPlugin interface
LoadPlugin load
LoadPlugin memory
LoadPlugin network
<Plugin interface>
    Interface "eth0"
    IgnoreSelected false
</Plugin>
<Plugin network>
    <Server "10.0.0.1" "25826">
    </Server>
</Plugin>

Be sure to replace 10.0.0.1 with the IP of your Logstash instance.

Detailsedit

 

authfileedit

  • Value type is string
  • There is no default value for this setting.

Path to the authentication file. This file should have the same format as the AuthFile in collectd. You only need to set this option if the security_level is set to Sign or Encrypt

nan_handlingedit

  • Value can be any of: change_value, warn, drop
  • Default value is "change_value"

What to do when a value in the event is NaN (Not a Number)

  • change_value (default): Change the NaN to the value of the nan_value option and add nan_tag as a tag
  • warn: Change the NaN to the value of the nan_value option, print a warning to the log and add nan_tag as a tag
  • drop: Drop the event containing the NaN (this only drops the single event, not the whole packet)

nan_tagedit

  • Value type is string
  • Default value is "_collectdNaN"

The tag to add to the event if a ‘NaN` value was found Set this to an empty string (’') if you don’t want to tag

nan_valueedit

  • Value type is number
  • Default value is 0

Only relevant when nan_handeling is set to change_value Change NaN to this configured value

prune_intervalsedit

  • Value type is boolean
  • Default value is true

Prune interval records. Defaults to true.

security_leveledit

  • Value can be any of: None, Sign, Encrypt
  • Default value is "None"

Security Level. Default is None. This setting mirrors the setting from the collectd Network plugin

typesdbedit

  • Value type is array
  • There is no default value for this setting.

File path(s) to collectd types.db to use. The last matching pattern wins if you have identical pattern names in multiple files. If no types.db is provided the included types.db will be used (currently 5.4.0).
