a. Included in z/OS.
b. Installable as Red Hat Package Manager (RPM).
You can use IBM zAware along with problem diagnosis solutions that are included in z/OS
with any large and complex z/OS installation with mission-critical applications and
middleware.
Notes:
IBM zAware uniquely analyzes messages in context to determine unusual behaviors.
IBM zAware uniquely understands and tunes its baseline to compare against your
current activity.
IBM zAware does not depend on other solutions or manual coding of rules, and is
always enabled to watch your system.

B.3 Understanding IBM zAware technology

IBM zAware creates a base model of system behavior by accessing prior system log
(SYSLOG) and applying mathematical modeling to these logs. The base model is then used
to compare with current SYSLOG for the monitored z/OS, and Linux on z Systems images.
This process helps in detecting unusual message pattern that might pinpoint deviations from
normal system behavior, which improves real-time diagnostics. IBM zAware automatically
manages the creation of the behavioral model that is used to compare current message log
data from the connected z/OS and Linux on z Systems instances.
