Monitoring

The following sections contain tips to troubleshoot Harvester Monitoring.

Monitoring is unusable

When the Harvester Dashboard is not showing any monitoring metrics, it can be caused by the following reasons.

Monitoring is unusable due to Pod being stuck in `Terminating` status

Harvester Monitoring pods are deployed randomly on the cluster Nodes. When the Node hosting the pods accidentally goes down, the related pods may become stuck in the Terminating status rendering the Monitoring unusable from the WebUI.

$ kubectl get pods -n cattle-monitoring-system

NAMESPACE                   NAME                                                     READY   STATUS        RESTARTS   AGE
cattle-monitoring-system    prometheus-rancher-monitoring-prometheus-0               3/3     Terminating   0          3d23h

...

Monitoring can be recovered using CLI commands to force delete the related pods. The cluster will redeploy new pods to replace them.

# Delete each none-running Pod in namespace cattle-monitoring-system.

$ kubectl delete pod --force -n cattle-monitoring-system prometheus-rancher-monitoring-prometheus-0

 pod "prometheus-rancher-monitoring-prometheus-0" force deleted

$ kubectl delete pod --force -n cattle-monitoring-system rancher-monitoring-admission-create-fwjn9

$ kubectl delete pod --force -n cattle-monitoring-system rancher-monitoring-crd-create-9wtzf

$ kubectl delete pod --force -n cattle-monitoring-system rancher-monitoring-grafana-d9c56d79b-ph4nz 

$ kubectl delete pod --force -n cattle-monitoring-system rancher-monitoring-grafana-d9c56d79b-t24sz

Wait for a few minutes so that the new pods are created and readied for the Monitoring dashboard to be usable again.

$ kubectl get pods -n cattle-monitoring-system 

NAME                                                     READY   STATUS     RESTARTS   AGE

Expand PV/Volume Size

Harvester integrates Longhorn as the default storage provider.

Harvester Monitoring uses Persistent Volume (PV) to store running data. When a cluster has been running for a certain time, the Persistent Volume may need to expand its size.

Based on the Longhorn Volume expansion guide, Harvester illustrates how to expand the volume size.

View Volume

From Embedded Longhorn WebUI

Access the embedded Longhorn WebUI according to this document.

The Longhorn dashboard default view.

Click Volume to list all existing volumes.

From CLI

You can also use kubectl to get all Volumes.

# kubectl get pvc -A
NAMESPACE                  NAME                                                                                             STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS         AGE

Scale Down a Deployment

To detach the Volume, you need to scale down the deployment that uses the Volume.

The example below is against the PVC claimed by rancher-monitoring-grafana.

Find the deployment in the namespace cattle-monitoring-system.

# kubectl get deployment -n cattle-monitoring-system
NAME                                    READY   UP-TO-DATE   AVAILABLE   AGE
rancher-monitoring-grafana              1/1     1            1           43h  // target deployment
rancher-monitoring-kube-state-metrics   1/1     1            1           43h
rancher-monitoring-operator             1/1     1            1           43h
rancher-monitoring-prometheus-adapter   1/1     1            1           43h

Scale down the deployment rancher-monitoring-grafana to 0.

# kubectl scale --replicas=0 deployment/rancher-monitoring-grafana -n cattle-monitoring-system

Check the deployment and the volume.

# kubectl get deployment -n cattle-monitoring-system
NAME                                    READY   UP-TO-DATE   AVAILABLE   AGE
rancher-monitoring-grafana              0/0     0            0           43h  // scaled down
rancher-monitoring-kube-state-metrics   1/1     1            1           43h
rancher-monitoring-operator             1/1     1            1           43h
rancher-monitoring-prometheus-adapter   1/1     1            1           43h

# kubectl get volume -A

longhorn-system   pvc-7c6dcb61-51a9-4a38-b4c5-acaa11788978   attached   degraded                 53687091200   harv31   43h
longhorn-system   pvc-b2b2c07c-f7cd-4965-90e6-ac3319597bf7   detached   unknown                  2147483648             43h  // volume is detached

Expand Volume

In the Longhorn WebUI, the related volume becomes Detached. Click the icon in the Operation column, and select Expand Volume.

Input a new size, and Longhorn will expand the volume to this size.

Scale Up a Deployment

After the Volume is expanded to target size, you need to scale up the aforementioned deployment to its original replicas. For the above example of rancher-monitoring-grafana, the original replicas is 1.

# kubectl scale --replicas=1 deployment/rancher-monitoring-grafana -n cattle-monitoring-system

Check the deployment again.

# kubectl get deployment -n cattle-monitoring-system
NAME                                    READY   UP-TO-DATE   AVAILABLE   AGE
rancher-monitoring-grafana              1/1     1            1           43h  // scaled up
rancher-monitoring-kube-state-metrics   1/1     1            1           43h
rancher-monitoring-operator             1/1     1            1           43h
rancher-monitoring-prometheus-adapter   1/1     1            1           43h

The Volume is attached to the new POD.

To now, the Volume is expanded to the new size and the POD is using it smoothly.

Fail to Enable `rancher-monitoring` Addon

You may encounter this when you install the Harvester v1.3.0 or higher version cluster with the minimal 250 GB disk per hardware requirements.

Reproduce Steps

Install the Harvester v1.3.0 cluster.
Enable the rancher-monitoring addon, you will observe:

The POD prometheus-rancher-monitoring-prometheus-0 in cattle-monitoring-system namespace fails to start due to PVC attached failed.

Workaround

Disable the rancher-monitoring addon if you have alreay enabled it.

All pods in cattle-monitoring-system are deleted but the PVCs are retained. For more information, see [Addons].

$ kubectl get pods -n cattle-monitoring-system
No resources found in cattle-monitoring-system namespace.

$ kubectl get pvc -n cattle-monitoring-system
NAME                                                                                             STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS         AGE

Delete the PVC named prometheus, but retain the PVC named alertmanager.

$ kubectl delete pvc -n cattle-monitoring-system prometheus-rancher-monitoring-prometheus-db-prometheus-rancher-monitoring-prometheus-0
persistentvolumeclaim "prometheus-rancher-monitoring-prometheus-db-prometheus-rancher-monitoring-prometheus-0" deleted

$ kubectl get pvc -n cattle-monitoring-system
NAME                                                                                             STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS         AGE

On the Addons screen of the Harvester UI, select ⋮ (menu icon) and then select Edit YAML.

As indicated below, change the two occurrences of the number 50 to 30 under prometheusSpec, and then save. The prometheus feature will use a 30GiB disk to store data.

Alternatively, you can use kubectl to edit the object.

kubectl edit addons.harvesterhci.io -n cattle-monitoring-system rancher-monitoring

        retentionSize: 50GiB // Change 50 to 30
        storageSpec:
          volumeClaimTemplate:
            spec:
              accessModes:
                - ReadWriteOnce
              resources:
                requests:
                  storage: 50Gi // Change 50 to 30
              storageClassName: harvester-longhorn

Enable the rancher-monitoring addon and wait for a few minutes..

All pods are successfully deployed, and the rancher-monitoring feature is available.

$ kubectl get pods -n cattle-monitoring-system

The ManagedChart object has a downstream object named Bundle, which has similar information.

Example:

$ kubectl get bundles -A
NAMESPACE     NAME                                          BUNDLEDEPLOYMENTS-READY   STATUS

When the issue exists and you start an upgrade, Harvester may return the following error message: admission webhook "validator.harvesterhci.io" denied the request: managed chart rancher-monitoring-crd is not ready, please wait for it to be ready.

Also, when you search for the objects marked as missing, you will find that they exist in the cluster.

Example:

$ kubectl get clusterrole rancher-monitoring-crd-manager

Root Cause

The objects that are marked as missing do not have the related annotations and labels required by the ManagedChart object.

Example:

One of the manually recreated object:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  annotations:
    meta.helm.sh/release-name: rancher-monitoring-crd
    meta.helm.sh/release-namespace: cattle-monitoring-system
    objectset.rio.cattle.io/id: default-mcc-rancher-monitoring-crd-cattle-fleet-local-system   # This required item is not in the above object.
  creationTimestamp: "2024-04-03T10:23:55Z"
  labels:
    app: rancher-monitoring-crd-manager
    app.kubernetes.io/managed-by: Helm
    objectset.rio.cattle.io/hash: 2da503261617e9ea2da822d2da7cdcfccad847a9    # This required item is not in the above object.
  name: rancher-monitoring-crd-manager
...
rules:
- apiGroups:
  - apiextensions.k8s.io
  resources:
  - customresourcedefinitions
  verbs:
  - create
  - get
  - patch
  - delete
  - update

Workaround

Patch the ClusterRole object rancher-monitoring-crd-manager to add the update operation.

$ cat > patchrules.yaml << EOF
rules:
- apiGroups:
  - apiextensions.k8s.io
  resources:
  - customresourcedefinitions
  verbs:
  - create
  - get
  - patch
  - delete
  - update
EOF

$ kubectl patch ClusterRole rancher-monitoring-crd-manager --patch-file ./patchrules.yaml --type merge

$ rm ./patchrules.yaml

Patch the marked as missing objects to add the required annotations and labels.

$ cat > patchhash.yaml << EOF
metadata:
  annotations:
    objectset.rio.cattle.io/id: default-mcc-rancher-monitoring-crd-cattle-fleet-local-system
  labels:
    objectset.rio.cattle.io/hash: 2da503261617e9ea2da822d2da7cdcfccad847a9
EOF

$ kubectl patch ClusterRole rancher-monitoring-crd-manager --patch-file ./patchhash.yaml --type merge

$ kubectl patch ClusterRoleBinding rancher-monitoring-crd-manager --patch-file ./patchhash.yaml --type merge

$ kubectl patch ServiceAccount rancher-monitoring-crd-manager -n cattle-monitoring-system --patch-file ./patchhash.yaml --type merge

$ kubectl patch ConfigMap rancher-monitoring-crd-manifest -n cattle-monitoring-system --patch-file ./patchhash.yaml --type merge

$ rm ./patchhash.yaml

Check the rancher-monitoring-crd ManagedChart object.

After a few seconds, the status of the rancher-monitoring-crd ManagedChart object changes to Ready.

$ kubectl get managedchart -n fleet-local rancher-monitoring-crd -oyaml
apiVersion: management.cattle.io/v3
kind: ManagedChart
metadata:
...
  name: rancher-monitoring-crd
  namespace: fleet-local
...
status:
  conditions:
  - lastUpdateTime: "2024-04-22T21:41:44Z"
    status: "True"
    type: Ready
...

Also, error indicators are no longer displayed for the downstream objects.

$ kubectl bundle -A
NAMESPACE     NAME                                          BUNDLEDEPLOYMENTS-READY   STATUS

fleet-local   mcc-rancher-monitoring-crd                    1/1

(Optional) Retry the upgrade (if previously unsuccessful because of this issue).
