Sink Output Configuration Options

edit

There are no special configuration options for this plugin, but it does support the Common Options.

Common Options

edit

The following configuration options are supported by all output plugins:

Setting	Input type	Required
`codec`	codec	No
`enable_metric`	boolean	No
`id`	string	No

`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.

`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 configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type. For example, if you have 2 sink outputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
  sink {
    id => "my_plugin_id"
  }
}

Variable substitution in the id field only supports environment variables and does not support the use of values from the secret store.
