Appendix B. IBM z Systems Advanced Workload Analysis Reporter (IBM zAware) 457
IBM zAware delivers sophisticated detection and diagnostic capabilities that identify when
and where to look for a problem. The cause of the anomalies can be difficult to determine.
High-speed analytics on large quantities of log data reduces the problem determination and
isolation efforts, time to repair, and impact to service levels. They also provide system
awareness for more effective monitoring.
Figure B-2 depicts how IBM zAware shortens the business impact of a problem.

The IBM zAware GUI also provides quick drill-down capabilities. You can view analytical data
that indicates which system is experiencing deviations in behavior, when the anomaly
occurred, and whether the message was issued out of context. The IBM zAware GUI fits into
existing monitoring structure and can also feed other processes or tools so that they can take
corrective action for faster problem resolution.
B.2.3 IBM z/OS Solutions to improve problem diagnostic procedures
Table B-1 shows how IBM zAware can be combined with other monitoring and problem
determination tools.

determination and trial and error.
More precise and early diagnosis can
shorten impact time and help you to
avoid a similar problem.
