Description
editRiemann is a network event stream processing system.
While Riemann is very similar conceptually to Logstash, it has much more in terms of being a monitoring system replacement.
Riemann is used in Logstash much like statsd or other metric-related outputs

You can see the author talk about it here:

map_fields
edit- Value type is boolean
-
Default value is
false
If set to true automatically map all logstash defined fields to riemann event fields. All nested logstash fields will be mapped to riemann fields containing all parent keys separated by dots and the deepest value.
As an example, the logstash event:
{ "@timestamp":"2013-12-10T14:36:26.151+0000", "@version": 1, "message":"log message", "host": "host.domain.com", "nested_field": { "key": "value" } }
Is mapped to this riemann event:
{ :time 1386686186, :host host.domain.com, :message log message, :nested_field.key value }
It can be used in conjunction with or independent of the riemann_event option. When used with the riemann_event any duplicate keys receive their value from riemann_event instead of the logstash event itself.
protocol
edit-
Value can be any of:
tcp
,udp
-
Default value is
"tcp"
The protocol to use UDP is non-blocking TCP is blocking
Logstash’s default output behaviour is to never lose events As such, we use tcp as default here
riemann_event
edit- Value type is hash
- There is no default value for this setting.
A Hash to set Riemann event fields (http://riemann.io/concepts.html).
The following event fields are supported:
description
, state
, metric
, ttl
, service
Tags found on the Logstash event will automatically be added to the Riemann event.
Any other field set here will be passed to Riemann as an event attribute.
Example:
riemann { riemann_event => { "metric" => "%{metric}" "service" => "%{service}" } }
metric
and ttl
values will be coerced to a floating point value.
Values which cannot be coerced will zero (0.0).
description
, by default, will be set to the event message
but can be overridden here.
Common options
editThese configuration options are supported by all output plugins:
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 riemann outputs.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
output { riemann { 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.
