Golden Signals - Latency

Golden Signals - Latency

Observability of modern cloud-native applications should provide deep visibility into an application’s performance, call attention to problems brewing through high fidelity alerts and provide an intuitive troubleshooting experience that shouldn’t require expert domain knowledge. With the advent of open-source approaches either based on OpenTelemetry or the ubiquitous Prometheus

Why My P99 < Average

Why My P99 < Average

We use both average and quantiles to measure latencies, but monitoring tools often have limitations with percentiles, which sometimes produce counterintuitive results. While investigating a latency problem, we noticed that Prometheus -- the system we use for monitoring -- reported the P99 latency for our app was less than the
