collate

edit

This is a community-maintained plugin! It does not ship with Logstash by default, but it is easy to install by running bin/logstash-plugin install logstash-filter-collate.

Collate events by time or count.

The original goal of this filter was to merge the logs from different sources by the time of log, for example, in real-time log collection, logs can be collated by amount of 3000 logs or can be collated in 30 seconds.

The config looks like this:

    filter {
      collate {
        size => 3000
        interval => "30s"
        order => "ascending"
      }
    }

Synopsis

This plugin supports the following configuration options:

Required configuration options:

collate {
}

Available configuration options:

Setting	Input type	Required	Default value
`add_field`	hash	No	`{}`
`add_tag`	array	No	`[]`
`count`	number	No	`1000`
`interval`	string	No	`"1m"`
`order`	string, one of `["ascending", "descending"]`	No	`"ascending"`
`periodic_flush`	boolean	No	`false`
`remove_field`	array	No	`[]`
`remove_tag`	array	No	`[]`

Details

`add_field`

edit

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 {
      collate {
        add_field => { "foo_%{somefield}" => "Hello world, from %{host}" }
      }
    }
[source,ruby]
    # You can also add multiple fields at once:
    filter {
      collate {
        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_tag`

edit

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 {
      collate {
        add_tag => [ "foo_%{somefield}" ]
      }
    }
[source,ruby]
    # You can also add multiple tags at once:
    filter {
      collate {
        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).

`count`

edit

Value type is number
Default value is 1000

How many logs should be collated.

`interval`

edit

Value type is string
Default value is "1m"

The interval is the time window which how long the logs should be collated. (default 1m)

`order`

edit

Value can be any of: ascending, descending
Default value is "ascending"

The order collated events should appear in.

`periodic_flush`

edit

Value type is boolean
Default value is false

Call the filter flush method at regular interval. Optional.

`remove_field`

edit

Value type is array
Default value is []

If this filter is successful, remove arbitrary fields from this event. Fields names can be dynamic and include parts of the event using the %{field} Example:

    filter {
      collate {
        remove_field => [ "foo_%{somefield}" ]
      }
    }
[source,ruby]
    # You can also remove multiple fields at once:
    filter {
      collate {
        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_tag`

edit

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 {
      collate {
        remove_tag => [ "foo_%{somefield}" ]
      }
    }
[source,ruby]
    # You can also remove multiple tags at once:
    filter {
      collate {
        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.
