Use Grafana to visualize service metrics

Preparation

1. Make default namespace managed by Kmesh

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

3. Install namespace granularity waypoint for default namespace

The above steps could refer to Install Waypoint | Kmesh

4. Deploy prometheus and garafana:

[root@ ~]# kubectl apply -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/prometheus.yaml
[root@ ~]# kubectl apply -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/grafana.yaml

Generate some continuous traffic between applications in the mesh

[root@ ~]# 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 service metrics

1. Use the port-forward command to forward traffic to grafana:

[root@ ~]# kubectl port-forward --address 0.0.0.0 svc/grafana 3000:3000 -n kmesh-system
Forwarding from 0.0.0.0:3000 -> 3000

2. View the dashboard from browser

Visit Dashboards>Kmesh>Kmesh Service Dashboard:

Cleanup

1. Remove prometheus and grafana:

[root@ ~]# kubectl delete -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/prometheus.yaml
[root@ ~]# kubectl delete -f https://raw.githubusercontent.com/kmesh-net/kmesh/main/samples/addons/grafana.yaml

2. If you are not planning to explore any follow-on tasks, refer to the Install Waypoint/Cleanup instructions to remove waypoint and shutdown the application.
