13.4.4.4. Nodes section
The Nodes section breaks down memory information per node to help identify imbalances. This section includes the following panels:
| Panel | Type | Description |
|---|---|---|
| Utilization - Actual Overcommit Level | Time series | Displays the per-node allocatable memory utilization minus the system-reserved memory. |
| Node Utilization - min | Gauge | Displays the lowest node utilization in the cluster. This panel also appears in the Summary section. |
| Plan - Pod Requests per Node | Time series | Shows the memory request fill level per node: the sum of all pod memory requests on a node divided by the node’s allocatable memory. |
| Node Requests - min/max | Stat | Displays the minimum and maximum pod request ratios per node. Use this panel to quickly assess the cluster’s remaining capacity to host new workloads. |
| Plan - Virtual Memory Commit Level | Time series | Displays the virtual memory commit ratio per node. The panel compares total active and assigned VM memory against the node’s available memory. |
| Node Virtual - min/max | Stat | Displays the minimum and maximum virtual commit levels per node. |
| Node - Pressure | Time series | Displays the memory PSI waiting rate per node. Each line represents one node to help you identify which nodes experience memory contention. |
| Node PSI - max | Gauge | Displays the highest PSI value across all nodes. PSI shows the amount of time applications are stalled or delayed waiting for memory resources. This panel also appears in the Summary section. |
