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:
[Just like any other setting]({{site.url}}{{site.baseurl}}/opensearch/configuration/), the alternative is to add the following line to `opensearch.yml` on each node and then restart the node:
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 Elasticsearch OSS (7.10.2 or lower).
These are the latest versions of Beats OSS with OpenSearch compatibility. For more information, see the [compatibility matrices](#compatibility-matrices).
Some users report compatibility issues with ingest pipelines on these versions of Beats. If you use ingest pipelines with OpenSearch, consider using the 7.10.2 versions of Beats instead.
