Java Runtime Metrics (OpenTelemetry)
To find out if this integration is available in your organization, see your Datadog Integrations page or ask your organization administrator.
To initiate an exception request to enable this integration for your organization, email [email protected].
Overview
The Java OpenTelemetry integration allows you to collect runtime metrics from your Java applications instrumented with OpenTelemetry.
Setup
See the dedicated documentation for Java Runtime Metrics via OpenTelemetry.
Recommended Collector Processors
The following metrics are emitted as cumulative counters by the OpenTelemetry Java SDK / agent. To convert them to per-second rates in Datadog, apply the Delta To Rate processor in your OpenTelemetry Collector pipeline:
jvm.cpu.timejvm.class.loadedjvm.class.unloaded
