Elastic Integration filter plugin

Elastic Integrations are designed to work with data streams and ECS-compatible output. Be sure that these features are enabled in the output-elasticsearch plugin.

Check out the output-elasticsearch plugin docs for additional settings.

When communicating over SSL, this plugin fully-validates the proof-of-identity presented by Elasticsearch using the system trust store. You can provide an alternate source of trust with one of:

You can also configure which aspects of the proof-of-identity are verified (see ssl_verification_mode).

When communicating over SSL, you can also configure this plugin to present a certificate-based proof-of-identity to the Elasticsearch cluster it connects to using one of:

You can configure this plugin to present authentication credentials to Elasticsearch in one of several ways:

During execution the Ingest pipeline works with a temporary mutable view of the Logstash event called an ingest document. This view contains all of the as-structured fields from the event with minimal type conversions.

It also contains additional metadata fields as required by ingest pipeline processors:

After execution completes the event is sanitized to ensure that Logstash-reserved fields have the expected shape, providing sensible defaults for any missing required fields. When an ingest pipeline has set a reserved field to a value that cannot be coerced, the value is made available in an alternate location on the event as described below.

Additionally, these Elasticsearch IngestDocument Metadata fields are made available on the resulting event if-and-only-if they were set during pipeline execution:

The encoded form of an API key that is used to authenticate this plugin to Elasticsearch.

Cloud authentication string ("<username>:<password>" format) is an alternative for the username/password pair and can be obtained from Elastic Cloud web console.

Cloud Id, from the Elastic Cloud web console.

When connecting with a Cloud Id, communication to Elasticsearch is secured with SSL.

For more details, check out the Logstash-to-Cloud documentation.

When running in a Logstash process that has Geoip Database Management enabled, integrations that use the Geoip Processor wil use managed Maxmind databases by default. By using managed databases you accept and agree to the MaxMind EULA.

You may instead configure this plugin with the path to a local directory containing database files.

This plugin will discover all regular files with the .mmdb suffix in the provided directory, and make each available by its file name to the GeoIp processors in integration pipelines. It expects the files it finds to be in the MaxMind DB format with one of the following database types:

A non-empty list of Elasticsearch hosts to connect.

Examples:

When connecting with a list of hosts, communication to Elasticsearch is secured with SSL unless configured otherwise.

A password when using HTTP Basic Authentication to connect to Elasticsearch.

Path to a PEM-encoded certificate or certificate chain with which to identify this plugin to Elasticsearch.

One or more PEM-formatted files defining certificate authorities.

This setting can be used to override the system trust store for verifying the SSL certificate presented by Elasticsearch.

Secure SSL communication to Elasticsearch is enabled unless:

Specifying ssl_enabled => true can be a helpful redundant safeguard to ensure this plugin cannot be configured to use non-ssl communication.

A path to a PKCS8-formatted SSL certificate key.

Password for the ssl_keystore_path.

A path to a JKS- or PKCS12-formatted keystore with which to identify this plugin to Elasticsearch.

A password or passphrase of the ssl_key.

A path to JKS- or PKCS12-formatted keystore where trusted certificates are located.

This setting can be used to override the system trust store for verifying the SSL certificate presented by Elasticsearch.

Password for the ssl_truststore_path.

Level of verification of the certificate provided by Elasticsearch.

SSL certificates presented by Elasticsearch are fully-validated by default.

A user name when using HTTP Basic Authentication to connect to Elasticsearch.

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 {
      elastic_integration {
        add_field => { "foo_%{somefield}" => "Hello world, from %{host}" }
      }
    }

    # You can also add multiple fields at once:
    filter {
      elastic_integration {
        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.

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 {
      elastic_integration {
        add_tag => [ "foo_%{somefield}" ]
      }
    }

    # You can also add multiple tags at once:
    filter {
      elastic_integration {
        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).

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.

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 elastic_integration filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

    filter {
      elastic_integration {
        id => "ABC"
      }
    }

Call the filter flush method at regular interval. Optional.

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 {
      elastic_integration {
        remove_field => [ "foo_%{somefield}" ]
      }
    }

    # You can also remove multiple fields at once:
    filter {
      elastic_integration {
        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.

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 {
      elastic_integration {
        remove_tag => [ "foo_%{somefield}" ]
      }
    }

    # You can also remove multiple tags at once:
    filter {
      elastic_integration {
        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.
