Threshold tuning

You can tune or use different collection methods for data collection items that place a high demand on system resources and yield high benefits.

In some products or subsystems, more than one method can be used to detect the same situation. Not all methods place the same demand on system resources.

IBM® Tivoli® OMEGAMON®, because it uses Boolean logic, provides more methods to detect complex situations. For example, a critical application suffers poor direct access storage device (DASD) response times. The cause of the poor response times is that the volume is being heavily accessed by multiple applications on other z/OS® partitions. You adjust the scope and frequency of numerous data collection settings to improve DASD response times.

IBM Tivoli OMEGAMON II uses indicator lights for thresholds and, typically, provides only one interval for each group of thresholds. With IBM OMEGAMON XE, you can have different intervals for each threshold, including warnings and critical thresholds. IBM OMEGAMON provides you with greater control and flexibility to help you reduce demand on system resources.
