Installing and configuring Grafana _ Monitoring

 

Procedure

1. In the Red Hat OpenShift Container Platform console, select Operators > OperatorHub and search for the Grafana operator that is provided by Red Hat OpenShift.
2. Install the Grafana operator for the openshift-user-workload-monitoring namespace.
3. Create an instance of Grafana.
   1. Select Operator > OperatorHub > Grafana Operator and then select the Grafana tab.
   2. Click Create Grafana.
   3. On YAML tab, enter the following text:

      apiVersion: integreatly.org/v1alpha1
      kind: Grafana
      metadata:
        name: mas-grafana
        namespace: openshift-user-workload-monitoring
      spec:
        ingress:
          enabled: true
        dataStorage:
          accessModes:
            - ReadWriteOnce
          size: 10Gi
          class: ocs-storagecluster-cephfs
        config:
          log:
            mode: "console"
            level: "warn"
          security:
            admin_user: "root"
            admin_password: "secret"
          auth:
            disable_login_form: False
            disable_signout_menu: True
          auth.anonymous:
            enabled: True
        dashboardLabelSelector:
          - matchExpressions:
              - {key: app, operator: In, values: [grafana]}
      

      A route is created, and the public URL is included in that route definition in the openshift-user-workload-monitoring namespace project.
4. Remember to update the subscription.yaml file and add the following configuration so that Grafana scans for the dashboard across the whole cluster:

   Config:
          env: 
          - name: "DASHBOARD_NAMESPACES_ALL" 
             value: "true"

   After an update, the subscription.yaml file looks like the following:

   apiVersion: operators.coreos.com/v1alpha1
           kind: Subscription
           metadata:
             name: grafana-operator
             namespace: "{{ grafana_namespace }}"
             labels:
               operators.coreos.com/grafana-operator.{{ grafana_namespace }}: ''
           spec:
             channel: v4
             installPlanApproval: Automatic
             name: grafana-operator
             source: community-operators
             sourceNamespace: openshift-marketplace
             config:
               env:
                 - name: "DASHBOARD_NAMESPACES_ALL"
                   value: "true"

5. Run the following command to grant the user permission.

   oc adm policy add-cluster-role-to-user cluster-monitoring-view -z grafana-serviceaccount

6. Run the following command to obtain the BEARER_TOKEN.

   - oc serviceaccounts get-token grafana-serviceaccount -n openshift-user-workload-monitoring

7. Create the GrafanaDataSource, which points to the Prometheus instance that you installed earlier.
1. Select the Grafana Operator > Installed operators > GrafanaDataSource tab.
2. Enter the following text and replace the ${BEARER_TOKEN} value with the value that you obtained in a previous step.

   apiVersion: integreatly.org/v1alpha1
   kind: GrafanaDataSource
   metadata:
     name: prometheus-grafanadatasource
     namespace:  openshift-user-workload-monitoring
   spec:
     datasources:
       - access: proxy
         editable: true
         isDefault: true
         jsonData:
           httpHeaderName1: 'Authorization'
           timeInterval: 5s
           tlsSkipVerify: true
         name: Prometheus
         secureJsonData:
           httpHeaderValue1: 'Bearer ${BEARER_TOKEN}'
         type: prometheus
         url: 'https://thanos-querier.openshift-monitoring.svc.cluster.local:9091'
     name: prometheus-grafanadatasource.yaml
