Figure 2.5. Cluster Utilization

2.4.1. CPU

The heatmap of the CPU utilization for a specific cluster that shows the average utilization of the CPU for the last 24 hours. Hovering over the heatmap displays the cluster name. Clicking on the heatmap navigates to the Hosts tab and displays the results of a search on a specific cluster sorted by CPU utilization. The formula used to calculate the usage of the CPU by the cluster is the average host CPU utilization in the cluster. This is calculated by using the average host CPU utilization for each host over the last 24 hours to find the total average usage of the CPU by the cluster.

2.4.2. Memory

The heatmap of the memory utilization for a specific cluster that shows the average utilization of the memory for the last 24 hours. Hovering over the heatmap displays the cluster name. Clicking on the heatmap navigates to the Hosts tab and displays the results of a search on a specific cluster sorted by memory usage. The formula used to calculate the memory usage by the cluster is the total utilization of the memory in the cluster in GB. This is calculated by using the average host memory utilization for each host over the last 24 hours to find the total average usage of memory by the cluster.
