Using SDSF to manage checks

For IBM Health Checker for z/OS, SDSF provides the CK command to display and manage checks. Using CK, you can issue one-time or temporary actions against active checks, including:

Displaying check information - action character D
Displaying check output - action character S
Shows check status and the message buffer for the check iteration.
Displaying check history in the IBM® Health Checker for z/OS® log stream- action character L
The check history panel (CKH) displays iterations of the check run during the lifetime of the IBM Health Checker for z/OS address space. Checks that ran before the last IBM Health Checker for z/OS restart are not accessible to SDSF and are not displayed, even if they are resident in the log stream.

This panel is only applicable if you have a log stream defined and setup for IBM Health Checker for z/OS.
Refreshing checks (deleting one or more checks, then adding all eligible checks) - action character E
Deleting checks - action character P
Running checks - action character R
Making temporary updates to check values in use, such as check interval, category, severity, or check message routing code. These updates will last until the check is refreshed (deleted and added again).- action character U
Deactivating checks - action character H
Changing check states

Like all SDSF primary displays CK can also be accessed from a pull-down when SDSF is running as an ISPF dialog. To display the action characters for the CK panel, use the SET ACTION SHORT or SET ACTION LONG command.

You can get sysplex-wide information about checks using SDSF's server and WebSphere® MQ. Starting with V1R13, SDSF uses XCF instead of Websphere MQ (if all systems are at V1R13 or higher) to display sysplex-wide information and no configuration is required.

You can also do the following with CK:

See just exceptions, using the CK E command instead of CK.
Browse a check using the S action character: When you are running SDSF under ISPF, you can also use the SB or SE action characters to browse the output with ISPF browse or edit.
Limit the checks shown with the S command. For example, S ABC* would show all checks that start with ABC. Reset the checks shown by typing S without parameters.
Filter checks shown using the filter option on the left hand side at the top of the screen. In this example, we filter for checks with names starting with CSV on system JA0:

You can turn filtering off by using the FILTER OFF command on the command line.
Sort the checks. For example, you can sort checks reporting exceptions in descending order using SDSF command SORT RESULT D.
Display checks using the D or DL action characters.
