The HPE Storage Array Exporter for Prometheus provides storage system information in the form of Prometheus metrics. It can be used in combination with HPE CSI Info Metrics Provider for Prometheus metrics to focus on storage resources used within a Kubernetes cluster.
- Kubernetes 1.18+ (most distributions)
- Helm 3 (3.2.0+)
The chart has these configurable parameters and default values.
| Parameter | Description | Default |
|---|---|---|
| acceptEula | Confirm your acceptance of the HPE End User License Agreement at https://www.hpe.com/us/en/software/licensing.html by setting this value to true. |
false |
| arraySecret | The name of a Secret in the same namespace as the Helm chart installation providing storage array access information: address (or backend), username, and password. |
hpe-backend |
| image.registry | The registry from which to pull container images. | quay.io |
| image.pullPolicy | Container image pull policy (Always, IfNotPresent, Never). |
IfNotPresent |
| logLevel | Minimum severity of messages to output (info, debug, trace, warn, error). |
info |
| metrics.disableIntrospection | Exclude metrics about the metrics provider itself, with prefixes such as promhttp, process, and go. |
false |
| service.type | The type of Service to create, ClusterIP for access solely from within the cluster or NodePort to provide access from outside the cluster (ClusterIP, NodePort). |
ClusterIP |
| service.port | The TCP port at which to expose access to storage array metrics within the cluster. | 9090 |
| service.nodePort | The TCP port at which to expose access to storage array metrics externally at each cluster node, if the Service type is NodePort and automatic assignment is not desired. | none |
| service.labels | Labels to add to the Service, for example to include target labels in a ServiceMonitor scrape configuration. | {} |
| service.annotations | Annotations to add to the Service, for example to configure it as a scrape target when using the Prometheus Helm chart's default configuration. | {} |
| serviceMonitor.enable | Create a ServiceMonitor custom resource (used with the Prometheus Operator). | false |
| serviceMonitor.targetLabels | List of labels on the service to add to the scraped metric. | [] |
The arraySecret parameter is required and has no default value. A Secret used by the HPE CSI Driver for Kubernetes can be reused without modification. Otherwise, use this example to create a new one.
The acceptEula value must be set to true, confirming your acceptance of the HPE End User License Agreement.
It's beneficial to understand how certain Service annotations and labels affect the deployment of the HPE Storage Array Exporter. Visit the official documentation to learn more.
helm repo add hpe-storage https://hpe-storage.github.io/co-deployments/
helm repo update
Use of a values.yaml file is recommended. Retrieve the values.yaml file for the latest version or for the specific version you will install:
helm show values hpe-storage/hpe-array-exporter --version X.Y.Z > myvalues.yaml
Edit the values according to the deployment environment, including identifying (or creating) an arraySecret and setting acceptEula to confirm your acceptance of the HPE End User License Agreement.
The latest release is installed by default. Add a --version or --devel option to install a specific version or the latest pre-release chart.
Use a customized values.yaml file:
kubectl create ns hpe-storage
helm install [RELEASE_NAME] hpe-storage/hpe-array-exporter -n hpe-storage -f myvalues.yaml
Or use command line options:
helm install [RELEASE_NAME] hpe-storage/hpe-array-exporter -n hpe-storage \
--set acceptEula=xxxx,arraySecret=my-array-secret
helm uninstall [RELEASE_NAME] -n hpe-storage
Visit the official documentation for guidance on usage.
