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).
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 OSS instead.
