Open Distro development has moved to OpenSearch. The Open Distro plugins will continue to work with legacy versions of Elasticsearch OSS, but we recommend upgrading to OpenSearch to take advantage of the latest features and improvements.
Trace Analytics provides a way to ingest and visualize OpenTelemetry data in Open Distro. This data can help you find and fix performance problems in distributed applications.
A single operation, such as a user clicking a button, can trigger an extended series of events. The front end might call a back end service, which calls another service, which queries a database, processes the data, and sends it to the original service, which sends a confirmation to the front end.
Trace Analytics can help you visualize this flow of events and identify performance problems.
