JaaS gives you four ways to see what it is doing in a cluster. Structured logs tell you what happened on a single request or reconcile; traces follow one operation across its spans; metrics aggregate behaviour into time series for dashboards and alerts; and alerts plus Kubernetes Events turn a sustained problem into a page or a notification.

Each pillar has its own page covering both the binary’s flags and the Helm chart keys that drive them:

• Logging — the log/slog logger, --log-level and --log-format, and reading JSON logs with kubectl logs and jq.
• Tracing — OTLP gRPC export to an OpenTelemetry collector, sampling, and viewing spans.
• Metrics — the Prometheus endpoint, the custom jaas_* metric family, scraping with a ServiceMonitor, and querying with PromQL.
• Alerting — the opt-in PrometheusRule alert catalog with its runbook links, plus Kubernetes Events routed through Flux’s notification-controller.

Logging applies to every mode JaaS runs in. Tracing, metrics, and alerting are operator-mode concerns and take effect once --enable-flux-integration is set (operator.enabled in the chart).
