Figure 11-4: Utilization data over time for an individual port on a device
The number of data points displayed, and the sampling interval are user-configurable
parameters, within the limitations of the device configuration. The defaults are:
• A 30-second sampling interval
• 50 data points displayed
However, in Figure 11-4, only 25 data points are displayed, because that is the maximum
number of values the BlackDiamond switch stores as historical data.
For an individual port, you can display individual errors in addition to utilization and
total errors.
◆ Select the tab at the bottom of the page to generate one of these displays. Figure 11-5 is
an example.
