8.1.5.4. Physical CPU Resource Monitoring of Resource Clusters
The CPU Dashboard can be used to monitor the physical CPU performance of the resource cluster. Figure 49 shows a sample dashboard that has been created using four widgets, which are illustrated in Figure 50, Figure 51, Figure 52, and Figure 53. These widgets include:
*Generic Scoreboard (Figure 50).
*Heat Map (Figure 51).
*Metric Graph (Figure 52).
*Health Status (Figure 53).

The Generic Scoreboard widget is at the bottom right of the dashboard in Figure 49. The selection is based on the resource cluster metric which is a sum of all host metrics in the cluster.

These threshold/ranges are only examples. These values should be based on the cluster design threshold values and the customer requirements.

The Heat Map widget shows the resource cluster physical CPU core utilization. This displays all the ESXi physical CPUs and cores in the resource cluster to identify hot spots on the physical CPUs. This configuration uses the core utilization metric and resource cluster tag to display the heat map data.

The Metric Graph widget is used to give a graph view of some of the CPU metrics. The view is customizable to display from last hour to last year. The graph can also display the dynamic thresholds for certain metrics. As an example, this widget displays the cluster CPU usage and cluster CPU wait.

The Health widget is used to display overall Resource Cluster Health. The widget can be configured to display data from the last hour to last month.
