SDSF

The SDSF task of z/OSMF lets you see key summary information about your sysplex, work with objects such as jobs and data sets, checks for IBM z/OS Health Checker, and issue system commands.

The SDSF task communicates with z/OS System Display and Search Facility (SDSF).

To select the SDSF task, expand the Jobs and Resources category in the navigation area and select SDSF.

You may not be authorized to all SDSF functions.

Scope of the data

The data displayed on the SDSF task is for the sysplex, or the JESplex for views showing JES data.

The title of the SDSF page includes the name of the sysplex for which SDSF is reporting data. For example, SDSF (PLEX1) indicates that data is being shown for the sysplex named PLEX1.

Common Filters

Use Common Filters to filter multiple views, including all of the views related to jobs. They do not affect the graphics under System Activity Summary. To see or modify the values for common filters, expand the Common Filters section. Then, click More to see all of the common filters.

Overview

The Overview tab is made up of sections that show information and provide links to other views. You can expand or collapse sections to show just the things that interest you.

System Activity Summary

System Activity Summary shows key system activity in graphical form.To view a text equivalent, click View Text.

System: The system for which information is being shown. To view data for a different system in the sysplex, select a system from the list. The system must be running a z/OS SDSF V2R2 server.

System Activity Percent Busy	z/OS Health Checks by Exception
Shows views of the percentage of time the CPU is busy. The views consist of LPAR and MVS/SRM views, and, if appropriate for your configuration, zAAP and zIIP views. Refer to About CPU use for more information. Spool shows the use of the JES spool.	Shows counts of exceptions, by severity, as well as counts of active and checks that are eligible to run. To see details about checks, use the z/OS Health Checks view. The types of severity are High, Medium, Low and None (no severity assigned). Note: A check may produce more than one exception.

z/OS Commands and Logs

The z/OS commands and logs functions let you work with z/OS commands and system responses.

Use the system command line to issue an MVS or other system command. Type the command or select it from the command history, then click Submit. The command is issued to the local system, which is indicated in the text that accompanies System command line. To issue a command to another system, use a ROUTE command.

For quick access to command reference information, click Help with command syntax. This help function uses the text in the command line (the command and first parameter) to display command syntax information that will help you complete the command.

Messages issued in response to the command are displayed in a pop-up window.
