Managing zxporter Resource Allocation and Cleanup

Increase Resource Requests for zxporter

By default, zxporter requests the following resources:

• Memory: 128Mi
• CPU: 200m

If you're running zxporter on a large Kubernetes cluster, you may need to allocate more resources. Use the following command to increase memory and CPU requests:

kubectl patch deployment devzero-zxporter-controller-manager -n devzero-zxporter --patch '{
  "spec": {
    "template": {
      "spec": {
        "containers": [
          {
            "name": "manager",
            "resources": {
              "requests": {
                "memory": "512Mi",
                "cpu": "500m"
              }
            }
          }
        ]
      }
    }
  }
}'
 
### Delete zxporter from your cluster
 
```bash
kubectl delete all --all -n devzero-zxporter

Metrics & Monitoring

• Exposes metrics via:
  • Prometheus Node Exporter
  • Kube-State-Metrics
  • PushGateway
• Resource usage is tracked for operator and Prometheus components.

Note: The operator reads only metadata and scheduler configuration required for workload analysis — no secrets or sensitive pod-level data is accessed.
