generator

edit

Generate random log events.

The general intention of this is to test performance of plugins.

An event is generated first

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.

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…​

message

edit
  • Value type is string
  • Default value is "Hello world!"

The message string to use in the event.

If you set this to stdin then this plugin will read a single line from stdin and use that as the message string for every event.

Otherwise, this value will be used verbatim as the event message.

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.

threads

edit
  • Value type is number
  • Default value is 1

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.
