Kiali Beyond the Graph – Troubleshooting Istio
summary
Kiali pulls Istio metrics, logs and traces plus the Kubernetes API to locate real faults: a trace scatter plot finds a handful of outliers up to 4.5s, drilling into Envoy config reveals a 3 second fixed delay injected 75% of requests and deleting the fault injection restores normal latency. Kiali also flags a VirtualService pointing to a non-existent Gateway (namespace/name swapped), validates the fix so curl returns 200, supports dry-run authorization testing via Envoy debug logs, and can replay graph history; traces via Jaeger and Tempo are supported.
