System Performance Monitoring
Supporting and maintaining an enterprise solution requires many steps and procedures. Depending on
the customer environment, the support procedures vary. System performance monitoring is one
procedure that helps maintain the system. This section provides a guide for monitoring Unified CCE to
ensure that the system is performing within system tolerances. System monitoring is especially critical
for customers as they expand or upgrade their system. The system should be monitored during times of
heavy activity.
The following system components are critical to monitor:
CPU
Memory
Disk
Network
The following list highlights some of the important counters for the critical system components, along
with their threshold values:
Monitoring the CPU
– %ProcessorTime; the threshold of this counter is 60%.
– ProcessorQueueLength; this value should not go above (2 ∗ (the total number of CPUs on the
system)).
Monitoring Memory
– % Committed Bytes; this value should remain less than (0.8 ∗ (the total amount of physical
memory)).
– Memory\Available MByte; this value should not be less than 16 MB.
– Memory\Pages/sec; the threshold for this counter is 10.
– Page File %usage; the threshold for this counter is 80%.
Monitoring the Disk Resources
– AverageDiskQueueLength; this value should remain less than (1.5 ∗ (the total number of disks
in the array)).
– %Disktime; this value should remain less than 60%.
Monitoring Network Resources
– NIC\bytes total/sec; this value should remain less than (0.3 ∗ (the physical size of the NIC)).
– NIC\Output Queue Length; the threshold for this counter is 1.

Note The above performance counters for CPU, memory, disk, and network are applicable to all servers
within the deployment. The recommended sample rate is 15 seconds.
