Trace Analytics provides a way to ingest and visualize OpenTelemetry data in Open Distro for Elasticsearch. 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.
