Latency +20%, failed health checks. Tools: Prometheus, Datadog, New Relic for metrics; Grafana for dashboards.

What is the recommended best practice for creating dashboards during a microservices deployment?

Best practice: deployment-specific dashboards, automated alerts, post-deployment review. Stop deployment if: errors
