Introduction
The de-facto monitoring stacks in 2026: Prometheus + Grafana + Loki + Tempo (self-hosted), Datadog / New Relic / Honeycomb (SaaS).
Understanding the topic
What to monitor — the four golden signals:
- 📈 Latency — p50/p95/p99 per endpoint.
- 🚦 Traffic — RPS, top endpoints by load.
- 🔥 Errors — 5xx rate, exception types.
- 🧠 Saturation — CPU, memory, GC pauses, DB pool, queue depth.
