IBM Health Checker for z/OS*, a foundation that simplifies and automates identifying configuration issues, is designed to do just that. By continuously comparing active values and settings to those suggested by IBM or defined by you, Health Checker alerts you of deviations from best practices before they impact your availability or cause outages. The resulting detailed messages also suggest actions to address exceptions.
Health Checker consists of the framework that manages functions and the health checks that evaluate specific settings and definitions. The architecture of the framework supports the nearly 200 checks written by IBM, along with scores more by ISVs and many specialized ones by customers themselves.
