How to: Common Issues
**Pod stuck in CrashLoopBackOff**
- Check logs: `kubectl logs -f deployment/kube-opex-analytics -n kube-opex-analytics`
- Verify RBAC permissions are correctly applied
- Ensure the service account has read access to pods and nodes

**No data appearing in dashboard**
- Wait at least 5-10 minutes for initial data collection
- Verify the pod can reach the Kubernetes API: check for connection errors in logs
- Confirm `KOA_K8S_API_ENDPOINT` is correctly set

**Metrics not appearing in Prometheus**
- Ensure the `/metrics` endpoint is accessible
- Check ServiceMonitor/PodMonitor configuration if using Prometheus Operator
- Verify network policies allow Prometheus to scrape the pod

**Pooling interval**
- By default, the polling interval to collect raw metrics from Kubernetes API or NVIDIA DCGM is 300 seconds (5 minutes).
- You can increase this limit using the variable `KOA_POLLING_INTERVAL_SEC`. Always use a multiple  300 seconds, as the backend RRD database is based on a 5-minutes resolution.
