Display OVN metrics from worker node
Metric containerCPU-AggregatedWorkers is NOT using the pod while fetching the data, so none of the existing panels in the dashboard are fetching OVN data from worker nodes as they use the pod in the metric's query i.e labels.pod.keyword: /ovnkube-node.*/ OVN IC is the default from OCP 4.14. So from 4.14 onwards, ovnkube-master pod doesn't exist. OVN now has 2 pods - ovnkube-control-plane & ovnkube-node. ovnkube-control-plane pod exists on the master nodes. This pod contains ovnkube-cluster-manager container with very minimal functionality and we can ignore metrics for this pod and the container. ovnkube-node pod exists on master, infra and worker nodes. This pod contains all OVN containers (both core OVN and OVNK). We are interested in metrics from the containers in this pod. So this patch creates separate panels for master, worker and infra nodes to show these containers CPU & memory usage. Note: We are using the Average instead of the Sum across all panels to ensure consistency with the worker node panel Signed-off-by: venkataanil <[email protected]>
