How ToAdmin
Cluster Monitoring
Monitor CPU, RAM, and disk usage across QuickStack cluster nodes.
Accessing the monitoring view
Go to Monitoring in the main menu to see CPU, memory, and disk usage across all cluster nodes.
Understanding metrics
Color coding
| Color | Threshold | Action |
|---|---|---|
| 🟢 Green | < 80% used | Healthy |
| 🟡 Yellow | 80–90% used | Monitor closely |
| 🔴 Red | > 90% used | Action needed |
When usage exceeds 90%, you may see: failed deployments, backup failures, app crashes, or system instability.
Disk metrics
Three disk metrics are shown per node:
- Used Disk Space — currently in use
- Free but Unusable Disk Space — free but reserved by the OS
- Available Disk Space — usable by deployed applications
Used + Free but Unusable = total "occupied" disk space on the node.
What to do when resources are high
| Resource | Over 90% action |
|---|---|
| CPU | Optimize workloads or add more nodes |
| RAM | Review container memory limits; add RAM or nodes |
| Disk | Run disk cleanup; expand disk or add nodes |
