20.8.4 Interpreting the data in a ring plot
Each segment, or slice, of a Performance Dashboard ring plot represents data for one managed
server. Each metric is shown in its own ring plot, and each server has its own segment of the
ring plot. The ring plots are arranged in rows and columns based on the window size and the
number of ring plots displayed.
Figure 20-11 illustrates the Performance Dashboard tool's default view, the percent of CPU load.
The center dial shows the current value.
Figure 20-11 Performance Dashboard default view: percent of CPU load
Figure 20-12 illustrates three ring plots that are displaying the CPU load (percentage), system
uptime (in days) metrics, and a partial view of the free root file system space (percentage). The
center of the ring shows the current value for the metric as well as the minimum, average, and
maximum values of the selected managed systems.
Table 20-3 (page 190) describes how to use
the mouse buttons to display additional metrics.
