9.8 IBM z Advanced Workload Analysis Reporter
IBM z Advanced Workload Analysis Reporter (IBM zAware) provides a solution for detecting
and diagnosing anomalies in z/OS and Linux on z Systems by analyzing software logs and
highlighting abnormal events. It represents a first in a new generation of “smart monitoring”
products with pattern-based message analysis.
IBM zAware runs as a firmware virtual appliance in a z13s LPAR. It is an integrated set of
analytic applications that creates a model of normal system behavior that is based on prior
system data. It uses pattern recognition techniques to identify unexpected messages in
current data from the z/OS or Linux on z Systems servers that it is monitoring. This analysis
of events provides nearly real-time detection of anomalies. These anomalies can then be
easily viewed through a graphical user interface (GUI).
