APM Instrumentationedit

Libbeat includes the Elastic APM Agent for instrumenting the publishing pipeline. Currently the Elasticsearch output is instrumented. APM can be enabled simply with setting the 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.
