Configuration for Logstash Output Opensearch Plugin

To run the Logstash Output Opensearch plugin, add following configuration in your logstash.conf file. Note: For logstash running with OpenSearch 2.12.0 and higher the admin password needs to be a custom strong password supplied during cluster setup.

output {
    opensearch {
        hosts       => ["hostname:port"]
        user        => "admin"
        password    => "<your-admin-password>"
        index       => "logstash-logs-%{+YYYY.MM.dd}"
    }
}

To run the Logstash Output Opensearch plugin using aws_iam authentication, refer to the sample configuration shown below:

output {
   opensearch {
          hosts => ["hostname:port"]
          auth_type => {
              type => 'aws_iam'
              aws_access_key_id => 'ACCESS_KEY'
              aws_secret_access_key => 'SECRET_KEY'
              region => 'us-west-2'
          }
          index  => "logstash-logs-%{+YYYY.MM.dd}"
   }
}

In addition to the existing authentication mechanisms, if we want to add new authentication then we will be adding them in the configuration by using auth_type.

Example Configuration for basic authentication: Note: For logstash running with OpenSearch 2.12.0 and higher the admin password needs to be a custom strong password supplied during cluster setup.

output {
    opensearch {
          hosts  => ["hostname:port"]
          auth_type => {
              type => 'basic'
              user => 'admin'
              password => '<your-admin-password>'
          }
          index => "logstash-logs-%{+YYYY.MM.dd}"
   }
}

To ingest data into a data stream through logstash, we need to create the data stream and specify the name of data stream and the op_type of create in the output configuration. The sample configuration is shown below: Note: For logstash running with OpenSearch 2.12.0 and higher the admin password needs to be a custom strong password supplied during cluster setup.

output {
    opensearch {
          hosts  => ["https://hostname:port"]
          auth_type => {
              type => 'basic'
              user => 'admin'
              password => '<your-admin-password>'
          }
          index => "my-data-stream"
          action => "create"
   }
}

Starting in 2.0.0, the aws sdk version is bumped to v3. In order for all other AWS plugins to work together, please remove pre-installed aws plugins and install logstash-integration-aws plugin as follows. See also https://github.com/logstash-plugins/logstash-mixin-aws/issues/38
