Observability

1. Verify the Cert-Manager is deployed and configured on the OpenShift Cluster. Please review the RedHat documentation for the procedure.

2. Verify the user workload monitoring is enabled and configured on the OpenShift Cluster. Please review RedHat documentation for the procedure to configure user workload monitoring on the OpenShift Cluster.

3. Enable Observability module in the CSM

   Use this command to create the ContainerStorageModule custom resource with Observability enabled.

   oc create -f csm-vxflexos.yaml
   

   Example:

   cat <<EOF> csm-vxflexos.yaml
   apiVersion: storage.dell.com/v1
   kind: ContainerStorageModule
   metadata:
     name: vxflexos
     namespace: vxflexos
   spec:
     driver:
       csiDriverType: "powerflex"
       configVersion: v2.15.1
     module:
     - name: observability
       enabled: true
       components:
       - name: otel-collector
         enabled: true
       - name: metrics-powerflex
         enabled: true
   EOF
   

   Verify the Observability Pods are created.

oc get pod -n vxflexos

NAME                                         READY   STATUS    RESTARTS   AGE
karavi-metrics-powerflex-69855dbdd5-5mshq     1/1     Running   0          2m54s
otel-collector-b496d8c4d-gp6zz               2/2     Running   0          2m55s 

Verify the Observability Services.

oc get svc -n vxflexos
NAME                           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)              AGE
karavi-metrics-powerflex        ClusterIP   172.30.169.86    <none>        2222/TCP             3m29s
otel-collector                 ClusterIP   172.30.127.237   <none>        55680/TCP,8443/TCP   3m29s 

4. Create Service Monitor to scrape the Observability module by the OpenShift Observability.

   Use this command to create the ServiceMonitor.

   oc apply -f smon-otel-collector.yaml
   

   Example:

   cat <<EOF> smon-otel-collector.yaml
   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     name: otel-collector
     namespace: vxflexos
   spec:
     endpoints:
     - path: /metrics
       port: exporter-https
       scheme: https
       tlsConfig:
         insecureSkipVerify: true
     selector:
       matchLabels:
         app.kubernetes.io/instance: karavi-observability
         app.kubernetes.io/name: otel-collector 
    EOF
   

Verify the ServiceMonitor is created.

oc get smon -n vxflexos
NAME             AGE
otel-collector   44h 

5. Verify the PowerFlex metrics are visible in the OpenShift Console.

   On the OpenShift Console, navigate to Observer and then Metrics, search for PowerFlex metrics.
