Viewing job performance statistics

 

A job's performance is important to anyone that uses a System i™ product because one job running poorly can affect other jobs on the system. To view potentially problematic jobs gives you the ability to prevent performance problems before they occur.

The Elapsed Performance Statistics window allows you to monitor a job's CPU use, disk I/O (hard disk input/output), page fault rates, average response times, and the number of interactive transactions. You can select an option in this window to refresh these statistics manually or on a schedule.

To display the elapsed performance statistics, follow the following instructions:

1. In iSeries™ Navigator, expand My Connections > server > Work Management > Active Jobs.

   You can view the performance of a job from any location within work management where you can see jobs. The Elapsed Performance Statistics window can be displayed from the Performance tab of a Job property window.

2. Right-click the job for which you want to display the performance statistics, and click Details > Elapsed Performance Statistics.

   You can refresh, reset, and schedule the performance statistics to automatically refresh.

   You can look at the elapsed performance statistics for more than one job at a time by opening multiple windows. This allows you to view multiple problematic jobs at one time. Each window holds the information for only one job.

The elapsed performance statistics is one way to view the performance of a job as it moves through the system. Another way to view jobs on the system is through the Management Central folder. You can monitor jobs in Management Central as well as monitor system performance and messages.
