Description
editGenerate random log events.
The general intention of this is to test performance of plugins.
An event is generated first
Generator Input Configuration Options
editThis plugin supports the following configuration options plus the Common Options described later.
Also see Common Options for a list of options supported by all input plugins.
count
edit- Value type is number
-
Default value is
0
Set how many messages should be generated.
The default, 0
, means generate an unlimited number of events.
lines
edit- Value type is array
- There is no default value for this setting.
The lines to emit, in order. This option cannot be used with the message setting.
Example:
input { generator { lines => [ "line 1", "line 2", "line 3" ] # Emit all lines 3 times. count => 3 } }
The above will emit line 1
then line 2
then line
, then line 1
, etc…
Common Options
editThe following configuration options are supported by all input plugins:
Details
edit
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 generator inputs.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
input { generator { id => "my_plugin_id" } }
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.
