Managing checks

Managing checks includes tasks such as:

Updating or overriding values defined for checks or check output, such as check interval, check severity, or check message routing code or WTO type
Making checks active or inactive
Requesting that the system process HZSPRMxx parmlib members
Adding checks
Deleting checks
Refreshing checks (deleting then adding) checks
Displaying check information

You can manage checks with the following interfaces:

Make dynamic, temporary changes to checks such as deactivating, adding, running, or temporarily updating check values, using:
- SDSF. See Using SDSF to manage checks.
- MODIFY command. See Making dynamic, temporary changes to checks.
Make persistent changes to checks that persist across check refreshes and restart of IBM® Health Checker for z/OS® using policies. You can define policies by specifying policy statements to be in your HZSPRMxx parmlib member or members, specifying the parmlib member is in the list of parmlib members being used at the start IBM Health Checker for z/OS, and activating the policy. See Making persistent changes to checks.

Table 1. When do I use which interface to manage checks?
How long will the change be in effect?	Task	Recommended interface
Dynamic, temporary changes See Making dynamic, temporary changes to checks.	I want to look at check output	SDSF or HZSPRINT
	I want to issue one-time actions against checks, including: Adding, and deleting checks Refreshing checks (deleting one or more checks, then adding all eligible checks) Displaying checks Running checks	SDSF or MODIFY `hzsproc`
	I want to experiment with temporary updates to check values, such as: Interval Severity Category Check message routing codes These changes will last until the check is refreshed (deleted and then add all eligible checks).	SDSF or MODIFY `hzsproc`,UPDATE
Persistent changes See Making persistent changes to checks.	I want to make changes that will persist across IBM Health Checker for z/OS restarts, such as permanent updates to check values on policy statements, adding local checks from the HZSPRMxx parmlib member, or turning on log stream support for IBM Health Checker for z/OS	HZSPRMxx statements, and then make sure that parmlib member(s) are in the list of parmlib members to be applied at IBM Health Checker for z/OS restart.
