I’ve written about workload groups in the past in Workload Group Configuration with IBM i 7.3 and Manage Workloads better with Workload Groups.
This blog reviews how to understand possible performance implications when using workload groups.

With the 7.3 release, IBM introduced historical performance data collection and the ability to view your historical data graphically with Graph History. With the recent Navigator service pack (HTTP Server Group PTF SF99722 Level 7 or later), graph history was expanded with stacked charts. Stacked charts allow you to display and compare a historical data metric over days, weeks, months, or years.

Recently I wrote about IBM i 7.3 System Monitor Enhancements and mentioned the default monitor collection interval was changed to 60 seconds. On the 7.2 release, the default collection interval was 15 seconds; IBM has recently changed the default on 7.2 to 60 seconds. For this change, you will need the Navigator service pack that was made available this past June. You can find the details of the required PTFs and PTF Groups on the developerWorks page for Navigator PTFs.

Last week I wrote about collecting performance data for database. This week I will review how you can visualize that database performance data with the Performance Data Investigator (PDI).
