APM Service Latency

The APM Service Latency chart displays response time metrics for a service across multiple percentiles and aggregations. You can view p50, p75, p90, p95, and p99 latencies along with average, minimum, maximum, and APDEX values. Use the metrics selector to switch between these different latency measurements to analyze service performance characteristics.

The Latency chart reports the latencies registered for the service: p50, p75, p90, p95, and p99 latencies, average latency, min latency, max latency, and APDEX.

  1. Click the metrics selector drop-down to choose between p50, p75, p90, p95, and p99 (default) latencies, average latency, min latency, max latency, and APDEX.
