🔒 Important Notice

Starting with the release of Container Storage Modules v1.16.0, this repository will no longer be maintained as an open source project. Future development will continue under a closed source model. This change reflects our commitment to delivering even greater value to our customers by enabling faster innovation and more deeply integrated features with the Dell storage portfolio.
For existing customers using Dell’s Container Storage Modules, you will continue to receive:

• Ongoing Support & Community Engagement
  You will continue to receive high-quality support through Dell Support and our community channels. Your experience of engaging with the Dell community remains unchanged.
• Streamlined Deployment & Updates
  Deployment and update processes will remain consistent, ensuring a smooth and familiar experience.
• Access to Documentation & Resources
  All documentation and related materials will remain publicly accessible, providing transparency and technical guidance.
• Continued Access to Current Open Source Version
  The current open-source version will remain available under its existing license for those who rely on it.

Moving to a closed source model allows Dell’s development team to accelerate feature delivery and enhance integration across our Enterprise Kubernetes Storage solutions ultimately providing a more seamless and robust experience.
We deeply appreciate the contributions of the open source community and remain committed to supporting our customers through this transition.

Observability Module for PowerScale

Metrics for PowerScale is part of Dell Container Storage Modules (CSM) for Observability, which provides Kubernetes administrators standardized approaches for storage observability in Kuberenetes environments.

Metrics for PowerScale is an open source distributed solution that provides insight into storage usage and performance as it relates to the CSI (Container Storage Interface) Driver for Dell PowerScale.

Metrics for PowerScale captures telemetry data of storage usage and performance obtained through the CSI Driver for Dell PowerScale. The Metrics service pushes it to the OpenTelemetry Collector, so it can be processed, and exported in a format consumable by Prometheus. Prometheus can then be configured to scrape the OpenTelemetry Collector exporter endpoint to provide metrics so they can be visualized in Grafana.

Building Metrics for PowerScale

If you wish to clone and build the Metrics for PowerScale service, a Linux host is required with the following installed:

Component	Version	Additional Information
Podman	v5.x.x	Podman installation
Docker Registry		Access to a local/corporate Docker registry
Golang	v1.25.x	Golang installation
gomock	v1.6.0	Go Mock
gosec		gosec
git	latest	Git installation
gcc		Run sudo apt install build-essential
kubectl	1.32-1.34	Ensure you copy the kubeconfig file from the Kubernetes cluster to the linux host. kubectl installation
Helm	v3.x.x	Helm installation

Once all prerequisites are on the Linux host, follow the steps below to clone and build the metrics service:

1. Clone the repository using the following command: git clone https://github.com/dell/csm-metrics-powerscale.git
2. Set the DOCKER_REPO environment variable to point to the local Docker repository, for example: export DOCKER_REPO=<ip-address>:<port>
3. In the csm-metrics-powerscale directory, run the following command to build the container image called csm-metrics-powerscale: make podman
4. Tag (with the "latest" tag) and push the image to the local Docker repository by running the following command: make tag push

Note: Linux support only. If you are using a local insecure docker registry, ensure you configure the insecure registries on each of the Kubernetes worker nodes to allow access to the local docker repository.

Testing the Observability Module for PowerScale

From the root directory where the repo was cloned, the unit tests can be executed using the following command:

make test

This will also provide code coverage statistics for the various Go packages.
