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 solution, we are adding a [version value](https://github.com/opensearch-project/OpenSearch/issues/693) to `opensearch.yml`. This change will let you set OpenSearch 1.x clusters to report version 7.10.2 (or any other arbitrary value). By reporting 7.10.2, the cluster will be able to connect with tools that check for a particular version number.
For a longer term solution, we plan to create an OpenSearch output plugin for Logstash. This plugin *does not exist yet*, but we've included it in the compatibility matrices below based on its expected behavior.
These versions of Logstash and Beats offer the best compatibility with OpenSearch. For more information, see the [compatibility matrices](#compatibility-matrices).
