Use Grafana to visualize kmesh performance monitoring

Preparation​

  1. Make default namespace managed by Kmesh

  2. Set relevant args:

    • Modify bpf/kmesh/probes/performance_probe.h by changing #define PERF_MONITOR 0 to #define PERF_MONITOR 1.
    • Change --enable-perfmonitor=false to --enable-perfmonitor=true in deploy/yaml/kmesh.yaml.

  3. Deploy bookinfo as sample application and sleep as curl client

  4. Install namespace granularity waypoint for default namespace

    The above steps could refer to Install Waypoint | Kmesh

  5. Deploy prometheus and garafana:

kubectl apply -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/prometheus.yaml
kubectl apply -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/grafana.yaml

Generate some continuous traffic between applications in the mesh​

kubectl exec deploy/sleep -- sh -c "while true; do curl -s http://productpage:9080/productpage | grep reviews-v.-; sleep 1; done"

Use grafana to visualize kmesh performance monitoring​

  1. Use the port-forward command to forward traffic to grafana:
kubectl port-forward --address 0.0.0.0 svc/grafana 3000:3000 -n kmesh-system
# Forwarding from 0.0.0.0:3000 -> 3000

  1. View the dashboard from browser

    Visit Dashboards > Kmesh > Kmesh performance monitoring:

Cleanup​

  1. Remove prometheus and grafana:
kubectl delete -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/prometheus.yaml
kubectl delete -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/grafana.yaml
