136 Performance and Power Monitoring

See Table 7-1 for a sample of how systems on Tom’s network may be utilized.

%CPU Utilization Time

is red for most of the samples collected (highly

used), it could mean that some application is over-utilizing the CPU. Tom

could consider moving this application to a system for which the

%CPU

Utilization Time

is green for most samples. In this case, from System 1 to

System 2. Tom could also move a memory module from System 1 to

System 2 to balance the load, or he could consider upgrading the hardware

or purchasing new memory modules.

If Tom monitors his systems over the

weekend

, and finds out the network and

CPU utilization counters are green (within the specified range) for 70% of the

samples, yellow (non-critical) for 20% of the samples, and red (critical) for

10% of the samples collected, it could mean that the network and CPU

utilization counters could be red for most samples during the

weekdays

The systems will be overloaded, and Tom could decide to add more systems

to his network or decide on some other form of load-balancing.
