Version: 3.0.0
Released on: 2016-09-10
Changelog
Compatible: 5.1.1.1, 5.0.0, 2.4.1, 2.4.0, 2.3.4

This plugin does not ship with Logstash by default, but it is easy to install by running bin/logstash-plugin install logstash-output-metriccatcher.

This output ships metrics to MetricCatcher, allowing you to utilize Coda Hale’s Metrics.

More info on MetricCatcher: https://github.com/clearspring/MetricCatcher

At Clearspring, we use it to count the response codes from Apache logs:

    metriccatcher {
        host => "localhost"
        port => "1420"
        type => "apache-access"
        fields => [ "response" ]
        meter => {
            "%{host}.apache.response.%{response}" => "1"
            }
    }

Details

edit

`biased`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value.

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`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.

`counter`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value. Example:

  counter => { "%{host}.apache.hits.%{response} => "1" }

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`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.

`gauge`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value.

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`host`

edit

Value type is string
Default value is "localhost"

The address of the MetricCatcher

`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.

`meter`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value.

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`port`

edit

Value type is number
Default value is 1420

The port to connect on your MetricCatcher

`timer`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value. Example:

  timer => { "%{host}.apache.response_time => "%{response_time}" }

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`uniform`

edit

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

The metrics to send. This supports dynamic strings like %{host} for metric names and also for values. This is a hash field with key of the metric name, value of the metric value.

The value will be coerced to a floating point value. Values which cannot be coerced will zero (0)

`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
