Figure 104 Performance Monitor graph
The graph shows the last 100 data samples and updates the samples based on the sample interval
setting.
The vertical axis uses a scale of 0 to 100. Graph data is automatically adjusted to fit the scale.
For example, if a statistic value was larger than 100, say 4,000.0, the system would scale it down
to 40.0 using a scaling factor of 0.01. If the statistic value is smaller than 10.0, for example 7.5,
the system would scale it up to 75 using a scaling factor of 10. The Scale column of the statistics
table shows the current scaling factor. If needed, you can change the scaling factor. For more
information, see
“Changing the scaling factor” (page 229) .
The horizontal axis shows either the local time or Greenwich Mean Time. The default setting is the
local time of the computer that is running the CMC. You can change this default to GMT. See
“Changing the sample interval and time zone” (page 225) . (This time zone setting is not related to
the management group time zone.)
For information about controlling the look of the graph, see “Changing the graph” (page 228) .
Performance monitor table
The performance monitor table displays a row for each selected statistic.
Figure 105 Performance Monitor table
The table shows information about the statistics selected for monitoring. The table values update
based on the sample interval setting.
To view the statistic definition, hold your mouse pointer over a table row.
Table 69 (page 221) defines each column of the Performance Monitor table.
