Starting with z/OS® V1R8, there are two ways to add your local check to the system:

• After you've written your check, use the ADD | ADDREPLACE CHECK parameter in an HZSPRMxx parameter to define check defaults and add the check. See "ADD or ADDREPLACE CHECK parameters".
• Write an authorized HZSADDCHECK exit routine running in the IBM Health Checker for z/OS address space, as described in Writing an HZSADDCHECK exit routine. The HZSADDCHECK exit routine describes the information about your local check or checks. The HZSADDCHECK exit routine invokes the HZSADDCK macro to:
  • Identify the check, providing values such as the check owner, check name, check routine name, and message table name.
  • Specifies the default values for the check, such as the check interval, check parameter, and check severity.
