What are the best leading indicators to standardize across teams?

Start with SLO burn rate (short and long windows), tail latency (p99/99.9), CPU throttling ratio, queue/consumer lag, and retry rate amplification. These move before customers complain and are portable across stacks.

We’re small. Is this overkill?

Automate the first two buttons: pause rollout and kill a flag. Use Argo Rollouts + Prometheus AnalysisTemplates and a simple webhook. You’ll save hours even with two services.

How do we avoid alert noise across 10+ teams?

Label consistently and route by team + playbook. Use burn-rate math to avoid flapping, set for: windows, and measure ‘alerts with no action’ as a KPI. Prune quarterly.

What if we’re on a legacy monolith?

You can still run canaries at the infra level (blue/green) and use feature flags for risky code paths. Leading indicators (burn rate, tail latency, throttling) still apply; wire Alertmanager to your deploy tool (Spinnaker, ArgoCD, or even a Jenkins job).

Which tools matter most?

Prometheus/Alertmanager for math and routing, OpenTelemetry for consistent labels, Argo Rollouts or Spinnaker for canaries and rollbacks, and LaunchDarkly/Unleash for flag kills. The tools are replaceable; the pattern (leading indicator → triage → automation) is not.
