Beyond Logs: Achieving Observability with Selenium and Grafana
summary
Shows how to push real-time Selenium Grid and test-run metrics into a single observability stack and get actionable alerts: Prometheus + Grafana + AlertManager + Pushgateway collects hub session counts, node counts and test metrics; a Selenium Grid exporter (Go) queries Grid GraphQL and exposes gauges; TestNG listeners push test-level metrics (passed/failed/skipped) for suites that often run an hour or more. Dashboards visualize health and AlertManager sends Slack notifications when app_metric == 0, enabling teams to diagnose and fix failures immediately.
