Find below the list of out-of-the-box tracing metrics sent by the Datadog Agent when APM is enabled. Import the APM monitoring dashboard in your Datadog account in order to get an out-of-the-box dashboard exploiting most of those metrics.
datadog.trace_agent.cpu_percent- Type: Gauge
CPU usage in terms of percentage of a core. For example, a value of 50 is half a core, or 200 is two cores. datadog.trace_agent.events.max_eps.current_rate- Type: Gauge
Count of APM Events per second received by the Agent datadog.trace_agent.events.max_eps.max_rate- Type: Gauge
Same as the Agent config’s max_events_per_second parameter. datadog.trace_agent.events.max_eps.reached_max- Type: Gauge
Is set to 1 every time max_events_per_second is reached, otherwise it’s 0. datadog.trace_agent.events.max_eps.sample_rate- Type: Gauge
