Polling frequency rate
The faster the polling rate, the more quickly the HCM GUI receives indications from the host. However, faster polling rates consume more of your system’s CPU and network resources and can therefore slow the system.
Controlling the polling frequency rate
To control port statistics polling, do one of the following from any of the Statistics dialog boxes.
1.Click the Start Polling check box to manually poll the port statistics.
2.Type the polling rate in the Polling Frequency in Seconds field. The range is between 5 and 3600 seconds. The default is 5 seconds.
3.Click the Stop Polling check box to stop port statistics polling.
4.Check the Keep Running Data check box to see the trend.
Resetting statistics
1.Click the Reset button on any of the Statistics dialog boxes. A warning dialog box, shown in Figure 17, displays.
