Job performance
The MainView for z/OS product monitors each address space (or job) in terms of its consumption of system resources and the delays that it experiences.
You can display this information for a single job, or for all of the jobs within a given workload, service class, domain—whatever criteria best suit your needs.
Workloads-jobs-being-served-by-system-resources explains how to obtain information about address space activity.
You can also take several management actions on active address spaces, such as cancel, kill, stop, dump, change the WLM service class, sample the CPU or I/O activity of programs and tasks, and display CPU use by subtasks. All of these actions are available by using easy-to-use line commands, menus, and overtype fields.
