sleepedit

Sleep a given amount of time. This will cause logstash to stall for the given amount of time. This is useful for rate limiting, etc.

 

Synopsisedit

This plugin supports the following configuration options:

Required configuration options:

}

Available configuration options:

Detailsedit

 

add_fieldedit

  • Value type is hash
  • Default value is {}

If this filter is successful, add any arbitrary fields to this event. Field names can be dynamic and include parts of the event using the %{field}.

Example:

filter {
  sleep {
    add_field => { "foo_%{somefield}" => "Hello world, from %{host}" }
  }
}
# You can also add multiple fields at once:
filter {
  sleep {
    add_field => {
      "foo_%{somefield}" => "Hello world, from %{host}"
      "new_field" => "new_static_value"
    }
  }
}

If the event has field "somefield" == "hello" this filter, on success, would add field foo_hello if it is present, with the value above and the %{host} piece replaced with that value from the event. The second example would also add a hardcoded field.

add_tagedit

  • Value type is array
  • Default value is []

If this filter is successful, add arbitrary tags to the event. Tags can be dynamic and include parts of the event using the %{field} syntax.

Example:

filter {
  sleep {
    add_tag => [ "foo_%{somefield}" ]
  }
}
# You can also add multiple tags at once:
filter {
  sleep {
    add_tag => [ "foo_%{somefield}", "taggedy_tag"]
  }
}

If the event has field "somefield" == "hello" this filter, on success, would add a tag foo_hello (and the second example would of course add a taggedy_tag tag).

everyedit

  • Value type is string
  • Default value is 1

Sleep on every N’th. This option is ignored in replay mode.

Example:

filter {
  sleep {
    time => "1"   # Sleep 1 second
    every => 10   # on every 10th event
  }
}

periodic_flushedit

  • Value type is boolean
  • Default value is false

Call the filter flush method at regular interval. Optional.

remove_fieldedit

  • Value type is array
  • Default value is []

If this filter is successful, remove arbitrary fields from this event. Example:

filter {
  sleep {
    remove_field => [ "foo_%{somefield}" ]
  }
}
# You can also remove multiple fields at once:
filter {
  sleep {
    remove_field => [ "foo_%{somefield}", "my_extraneous_field" ]
  }
}

If the event has field "somefield" == "hello" this filter, on success, would remove the field with name foo_hello if it is present. The second example would remove an additional, non-dynamic field.

remove_tagedit

  • Value type is array
  • Default value is []

If this filter is successful, remove arbitrary tags from the event. Tags can be dynamic and include parts of the event using the %{field} syntax.

Example:

filter {
  sleep {
    remove_tag => [ "foo_%{somefield}" ]
  }
}
# You can also remove multiple tags at once:
filter {
  sleep {
    remove_tag => [ "foo_%{somefield}", "sad_unwanted_tag"]
  }
}

If the event has field "somefield" == "hello" this filter, on success, would remove the tag foo_hello if it is present. The second example would remove a sad, unwanted tag as well.

replayedit

  • Value type is boolean
  • Default value is false

Enable replay mode.

Replay mode tries to sleep based on timestamps in each event.

The amount of time to sleep is computed by subtracting the previous event’s timestamp from the current event’s timestamp. This helps you replay events in the same timeline as original.

If you specify a time setting as well, this filter will use the time value as a speed modifier. For example, a time value of 2 will replay at double speed, while a value of 0.25 will replay at 1/4th speed.

For example:

filter {
  sleep {
    time => 2
    replay => true
  }
}

The above will sleep in such a way that it will perform replay 2-times faster than the original time speed.

timeedit

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

The length of time to sleep, in seconds, for every event.

This can be a number (eg, 0.5), or a string (eg, %{foo}) The second form (string with a field value) is useful if you have an attribute of your event that you want to use to indicate the amount of time to sleep.

Example:

filter {
  sleep {
    # Sleep 1 second for every event.
    time => "1"
  }
}
