Tracing with OpenTelemetry on OpenSearch
TL;DR This post is for architects who want to add tracing to Aiven for OpenSearch and need to know what it takes to run the pipeline. Aiven for OpenSearch includes Trace Analytics in OpenSearch Dashboards, so you can follow a request across services, see which services call which, and open the logs a slow span wrote. OpenTelemetry collects the traces, and Data Prepper writes them to the span and service map indexes that Trace Analytics reads.
