Libbeat includes the Elastic APM Agent for instrumenting the publishing pipeline.
Currently the Elasticsearch output is instrumented. APM can be enabled simply with
ELASTIC_APM_ACTIVE environment variable to
true when starting the beat.
To make tracing possible, the
Publish method of the
Client interface takes a
Context object as first argument. That
Context is intended for propagating
request-scoped values, not for cancellation.
