Version: 3.0.2
Released on: 2016-07-14
Changelog
Compatible: 5.1.1.1, 5.0.0, 2.4.1, 2.4.0, 2.3.4

The Nagios output is used for sending passive check results to Nagios via the Nagios command file. This output currently supports Nagios 3.

For this output to work, your event must have the following Logstash event fields:

nagios_host
nagios_service

These Logstash event fields are supported, but optional:

nagios_annotation
nagios_level (overrides nagios_level configuration option)

There are two configuration options:

commandfile - The location of the Nagios external command file. Defaults to /var/lib/nagios3/rw/nagios.cmd
nagios_level - Specifies the level of the check to be sent. Defaults to CRITICAL and can be overriden by setting the "nagios_level" field to one of "OK", "WARNING", "CRITICAL", or "UNKNOWN"
```
    output{
      if [message] =~ /(error|ERROR|CRITICAL)/ {
        nagios {
          # your config here
        }
      }
    }
```

Details

`codec`

edit

Value type is codec
Default value is "plain"

The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output, without needing a separate filter in your Logstash pipeline.

`commandfile`

edit

Value type is string
Default value is "/var/lib/nagios3/rw/nagios.cmd"

The full path to your Nagios command file.

`enable_metric`

edit

Value type is boolean
Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

`id`

edit

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

Add a unique ID to the plugin instance, this ID is used for tracking information for a specific configuration of the plugin.

output {
 stdout {
   id => "ABC"
 }
}

If you don’t explicitely set this variable Logstash will generate a unique name.

`nagios_level`

edit

Value can be any of: 0, 1, 2, 3
Default value is "2"

The Nagios check level. Should be one of 0=OK, 1=WARNING, 2=CRITICAL, 3=UNKNOWN. Defaults to 2 - CRITICAL.

`workers`

edit

Value type is string
Default value is 1

TODO remove this in Logstash 6.0 when we no longer support the :legacy type This is hacky, but it can only be herne
