Reviewing MeasureWare Data

If you run the HP MeasureWare agent on all the NNM systems and use ITO to manage them, you will then receive performance alarms from these systems. Typical resource alarms include:

• swap space utilization

• disk I/O rate

• CPU utilization

• LAN errors

• LAN throughput

• RAM utilization

To balance these alarms against the amount of user activity, it may be prudent to program ITO to monitor the number of ovw sessions on each NNM system. Experience suggests that a successful NNM deployment attracts more users than originally anticipated. If resource alarms occur too frequently during the busy hour and the number of active sessions is greater than expected, then some platform tuning in the form of additional CPUs, RAM, or disks may be ...
