Use Grafana to visualize kmesh perofrmance 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:

[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 kmesh performance monitoring

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

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
