The two main
objectives of Cisco HCS capacity reporting are:
- Identify immediate
performance concerns.
- Provide trending
information based on usage patterns to ensure timely upgrades.
Cisco HCS collects
metrics in the following areas on a per-VM basis, regardless of the
applications on the VM:
- CPU (Average, Peak, Ready
Time)
- Memory (Average, Peak,
Swap, Overhead)
- Disk Usage (Latency and
IOPS)
Network
infrastructure metrics are also important during network integration through a
fresh install, or when growth occurs in the network that requires software and
hardware upgrades. Depending on the topology of the network deployed, overall
system capacity in terms of supported subscribers and customers can vary. You
must track network infrastructure metrics regularly to manage potential growth
as the Cisco HCS system expands.
Monitoring
capacity metrics will help you identify bottlenecks in the system will become
evident, and perform capacity planning to ensure that bottlenecks do not
inhibit system resources or end-user experience.
The following tables
provide a list of metrics that are important to monitor and trend on a regular
basis.
