metriccatcher

edit

This is a community-maintained plugin! It does not ship with Logstash by default, but it is easy to install by running bin/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"
            }
    }

Synopsis

This plugin supports the following configuration options:

Required configuration options:

metriccatcher {
}

Available configuration options:

Setting	Input type	Required	Default value
`biased`	hash	No
`codec`	codec	No	`"plain"`
`counter`	hash	No
`gauge`	hash	No
`host`	string	No	`"localhost"`

`workers`	number	No	`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)

`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

`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 number
Default value is 1

The number of workers to use for this output. Note that this setting may not be useful for all outputs.
