Router, PG instances are visible in the Instance list of the Router's Add Counter
window. Notice that the Instance list includes a pseudo-instance called _Total. If
_Total is selected, each selected counter will contain the sum of the values for all
the instances.
Registry Settings and Risks
There are overheads in maintaining ICM QoS counters. The application needs to
have a block of memory that stores current counter data, and periodically it must
update these values. Furthermore, synchronizing access to the counter values adds
serious burdens to the system. For these reasons, the performance monitoring
feature is turned off by default. To turn on the feature, change the following
registry key value to 1 and cycle the application process.
HKEY_LOCAL_MACHINE\Software\Cisco Systems, Inc.\<instance>\<node>\DMP\
CurrentVersion\EnablePerformanceMonitor
System Performance Monitor introduces overheads itself and the overheads
depend on the periodic update interval, which is set as the minimum 1 second by
default. This interval should be set reasonably high to minimize the impact on the
system.
Charting QoS Values
To chart performance values associated with links between the Peripheral
Gateway Agent (PG Agent) and the Central Controller Agent (CC Agent),
perform the following steps from the Add Counters dialog box:
3. From the Performance Object drop-down list, select Cisco ICM QoS.
4. From the Instance list, select the link that you want to chart.
On the PG agent side, instance names are listed in the following format:
<from node name> PGAgent to CCAgent <A or B>
On the Central Controller side, instance names are listed in the following
format:
<from node name> CCAgent to Dev <device id>
5. From the Counter list, select the counter values that you wish to chart
(Table 5-2).
