Figure 1 Resource distribution overview

• Click Select Metric to customize the metrics to be viewed. Table 1 shows all the metrics. After selecting a metric, the distribution of hosts in the corresponding range is displayed.
• When you move the cursor to a color block, the number of hosts in the current CPU usage range is displayed, as shown in Figure 1. Click a column to display the hosts in the current range.
  • When you click the host name of a specified host, the page showing the host detailed information is displayed.
  • When you click View Trends of a specified host, the page showing the maximum, average, and minimum cluster values, and host values of the current metric are displayed. You cannot view the trends when the metric of the current cluster is Host CPU-Memory-Disk Usage.
• Click Export Data to export the metric maximum, minimum, and average values of all nodes in the current cluster in the selected time range.
