+# Observability
+
+Elasticsearch emits logs as described in the [public logging docs][], and exposes a good deal of information about its inner workings using
+all its management and stats APIs. Elasticsearch also integrates with the [Elastic APM Java agent][] to perform distributed tracing (as
+described in [TRACING.md][]) and metrics collection (as described in [METERING.md][]). This agent exposes the data it collects to an
+[OpenTelemetry][] service such as [Elastic APM Server][].
