CHAPTER 7 RESOURCE MANAGEMENTFigure 7-15. Intradatabase IORM calculationsIORM Monitoring and MetricsI/O performance metrics are collected and maintained for IORM in the storage cell. These metricsmay be used to determine the effects your IORM plan has on the databases, categories, and resourcegroup resource directives you defined in your environment. For example, you can see how much I/O aparticular database is using compared to other databases. By observing the actual I/O distribution foryour IORM consumer groups, you can determine whether adjustments need to be made to provideadequate I/O resources for applications using your databases. In this section we’ll look at how thesemetrics are organized and tap into the valuable information stored there.Understanding IORM MetricsWhen an IORM plan is defined in the storage cell, cellsrv creates I/O consumer groups correspondingto the I/O directives defined in the Intradatabase, Category, and Intradatabase IORM Plans. Forexample, the following I/O consumer groups were created in the storage cells from our IORM plan forthe SCRATCH and SNIFF databases:219
