zAware

Contributor(s): Robert Crawford

zAware is a mainframe monitor for IBM’s zEnterprise EC12 mainframe server. 

 zAware, which runs as firmware in a separate logical partition, is designed to read operations log (OPERLOG) messages and compile a behavioral pattern unique to that particular z/OS system.  Having a baseline of normal  activity allows zAware to recognize when out-of-the-ordinary things happen, such as unexpected messages showing up, expected messages failing to show up or normally infrequent messages appearing in large volume.

zAware, which stands for z Advanced Workload Analysis Reporter, is not bundled with the zEC12.  It must be ordered and paid for separately and requires a dedicated direct access storage device (DASD).
