Description

edit

Read RELP events over a TCP socket.

For more information about RELP, see http://www.rsyslog.com/doc/imrelp.html

This protocol implements application-level acknowledgements to help protect against message loss.

Message acks only function as far as messages being put into the queue for filters; anything lost after that point will not be retransmitted

edit

Value type is path

The SSL CA certificate, chainfile or CA path. The system CA path is automatically included.

`ssl_cert`

edit

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

SSL certificate path

`ssl_enable`

edit

Value type is boolean

Enable SSL (must be set for other ssl_ options to take effect).

Common Options

edit

The following configuration options are supported by all input plugins:

Setting	Input type	Required
`add_field`	hash	No
`codec`	codec	No
`enable_metric`	boolean	No
`id`	string	No
`tags`	array	No
`type`	string	No

Details

edit

`add_field`

edit

Value type is hash
Default value is {}

Add a field to an event

`codec`

edit

Value type is codec
Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, 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 relp inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  relp {
    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.

`tags`

edit

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

Add any number of arbitrary tags to your event.

This can help with processing later.

`type`

edit

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

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
