APM metrics sent by the Datadog Agent

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.

METRIC NAMETYPEDESCRIPTION
datadog.trace_agent.cpu_percentGaugeCPU usage (in cores), e.g. 50 (half a core), 200 (two cores), 250 (2.5 cores)
datadog.trace_agent.events.max_eps.current_rateGaugeCount of APM Events per second received by the Agent
datadog.trace_agent.events.max_eps.max_rateGaugeSame as the Agent config’s max_events_per_second parameter.
datadog.trace_agent.events.max_eps.reached_maxGaugeIs set to 1 every time max_events_per_second is reached, otherwise it’s 0.
datadog.trace_agent.events.max_eps.sample_rateGaugeSample rate applied by the Agent to Events it received
datadog.trace_agent.heap_allocGaugeHeap allocations as reported by the Go runtime.
datadog.trace_agent.heartbeatGaugeIncrement by one every 10 seconds.

datadog.trace_agent.obfuscationsCountIncrement by one every time an SQL obfuscation happens.
datadog.trace_agent.panicGaugeIncrement by one on every code panic.
datadog.trace_agent.ratelimitGaugeIf lower than 1, it means payloads are being refused due to high resource usage (cpu or memory).
