Abstract for IBM Health Checker for z/OS
Purpose of this document
This document presents the information you need to install, use, and develop checks for IBM® Health Checker for z/OS®. IBM Health Checker for z/OS is a component of MVS that identifies potential problems before they impact your availability or, in worst cases, cause outages. It checks the current active z/OS and sysplex settings and definitions for a system and compares the values to those suggested by IBM or defined by you. It is not meant to be a diagnostic or monitoring tool, but rather a continuously running preventative that finds deviations from best practices. IBM Health Checker for z/OS produces output in the form of detailed messages to let you know of both potential problems and suggested actions to take.
