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 box to manually poll the port statistics.

2. Type the polling rate in the Polling Frequency in Seconds text box. The range is between five 

and 3600 seconds. The default is five seconds.

3. Click the Stop Polling box to stop port statistics polling.

4. Check the Keep Running Data check box to see the trend.
