IBM i Job Watcher
IBM® i Job Watcher provides for the collection of job data for any or all jobs, threads, and tasks on the system. It provides call stacks, SQL statements, objects being waited on, Java™ JVM statistics, wait statistics and more which are used to diagnose job related performance problems.
IBM i Job Watcher is similar in sampling function to the CL commands WRKACTJOB and WRKSYSACT in that each refresh computes delta information for the ending interval. The data collected from the jobs, threads, or tasks being watched is done so in a non-intrusive manner.
IBM i Job Watcher can be configured and managed through the IBM Navigator for i Performance interface or CL commands.
