This daily report indicates that the CPU resource is idle most of the time for this period. This result is

normal for a business that only uses its computers from 9:00 a.m. to 5:00 p.m. During the week, the

CPU usage does not vary by more than about 10%, which is a good indication that the current

configuration is working. However, the report for Saturday, July 10 has what appears to be an

anomaly. Group 2 is taking up almost all the machine. On closer examination though, the

administrator finds that the total seconds used is about the same as every other day, but all the other

groups went virtually idle on the weekend. This application might be able to do its job even faster if

the administrator took off the memory cap for group 2 only on the weekends. Because there is no

contention, a second configuration file could be created to repeal all memory records and change the

CPU allocations for the weekend.

Another item to note in the report is that group 1, OTHERS, has bursts of high activity relative to its

normal levels. It might be worthwhile to do a CPU conflict report, excluding known applications, to

discover who the offender is.

Conclusion

All aspects of business today are under increasing pressure to do more with fewer resources. This is

especially true in the IT environment. IT departments must meet service level agreements, provide

superior service to disparate departments, and provision and maintain the information engine that

helps enable company growth. It is clear that reducing system management costs and improving

computer system resource utilization is an important part of the solution.

HP Process Resource Manager is a key technology for providing an adaptive approach to IT that

pools and shares resources so that utilization is optimized and supply automatically meets demand.
