Historically, many multiple popular agents and ingestion tools have worked with Elasticsearch OSS, such as Beats, Logstash, Fluentd, FluentBit, and OpenTelemetry. OpenSearch aims to continue to support a broad set of agents and ingestion tools, but not all have been tested or have explicitly added OpenSearch compatibility.
As an intermediate compatibility solution, OpenSearch has a setting that instructs the cluster to return version 7.10.2 rather than its actual version.
If you use clients that include a version check, such as recent versions of Logstash OSS or Filebeat OSS, enable the setting:
You can download the OpenSearch output plugin for Logstash from [OpenSearch downloads](https://opensearch.org/downloads.html). The Logstash output plugin is compatible with OpenSearch and open source versions of Elasticsearch (7.10.2 or lower).
These versions of Beats offer the best compatibility with OpenSearch. For more information, see the [compatibility matrices](#compatibility-matrices).
