Resetting Measurements

The clr-meas MML command resets the measurement counters. This command resets an individual
counter or all counters in a counter group. The following are valid counter groups:
•
•
•
For more information about the clr-meas command, see
Command Reference."

Retrieving Counters

Use the rtrv-ctr MML command to retrieve measurement counters. This command displays the
measurements for a counter group. Valid counter groups are RAS, Q.931, and H.245. For more
information about the rtrv-ctr command, see
Reference."
Overload
The system continuously checks call totals and CPU utilization. Each of these values is compared to
predefined limits. Three call total limits are available. Each limit has a hysteresis value and an alarm
associated with it. When the call total reaches the limit, an alarm is raised. When the call total falls below
the limit minus the hysteresis value, the alarm is cleared after the appropriate recovery action is taken.
Cisco HSI supports the following three levels of overload:
•
•
•
The following factors can trigger any one of the overload levels:
