Update the z/OSMF log level

To change the log level for one or more z/OSMF services, select the z/OSMF Diagnostic Assistant icon in the z/OSMF desktop.

1. Select the z/OSMF Diagnostic Assistant icon in the z/OSMF desktop.
   
2. Select the tab Set the z/OSMF logging level.
   The services table shows the z/OSMF services for which the log level can be set. Initially, the table is empty. To modify the log level for a particular z/OSMF service, you must first add the service to this table.
3. To add a z/OSMF service to the table, select Add service.
   The Add service option displays when all service checkboxes are cleared. A filter function is provided for string searches.
   If a z/OSMF service is not displayed in the list, the service is not enabled on your system. To enter the name of a z/OSMF service that you plan to enable later, select Others.
4. In the Add Service window, select the z/OSMF services for which you want to modify the log level.
5. Click OK.
   The services table is updated to show the package name and current log level for the z/OSMF services that you selected.
   You can edit the package names to include multiple packages for a service. Use a colon (':') to separate each package name. For example:

   com.ibm.zoszmf.cp.a:com.ibm.zoszmf.cp.b

6. For each z/OSMF service, specify the log level that you want to enable.
   • Select the z/OSMF service, then select a log level from the Log Level column. The valid log levels are described in Table 1. When you finish setting log levels for the services, click Set to apply your changes for the selected services. A notification message is displayed to confirm that the log levels are changed. Notice that a count of notification messages is displayed to the right of the bell icon in the upper right corner of the page. To view your notification messages, click the bell icon.
   • To deselect a z/OSMF service, click Cancel.
   • To remove a service from the table, select the service and click Delete.
   • To restore all of the z/OSMF service log levels to the IBM default values, click Restore Defaults. For more information about the z/OSMF default log levels, see the description of the LOGGING option of the IZUPRMxx parmlib member in IBM z/OS Management Facility Configuration Guide.

   Table 1. Valid log levels for the z/OSMF server.

   Log level	Content / Significance
   INFO	General information outlining overall task progress.
   FINE	Trace information - General trace.
   FINER	Trace information - Detailed trace, which includes general trace plus method entry, exit, and return values.
   FINEST	Trace information - A more detailed trace that includes all the detail that is needed to debug problems.
   SEVERE	Task cannot continue but component, application, and server can still function. This level can also indicate an impending unrecoverable error.
   WARNING	Potential error or impending error. This level can also indicate a progressive failure (for example, the potential leaking of resources).
   ALL	All events are logged. If you create custom levels, ALL includes those levels, and can provide a more detailed trace than finest.
   CONFIG	Configuration change or status.
   OFF	Logging is turned off.

7. When you are done with your selections, click Save.
   z/OSMF sets all of the enabled services to INFO, then applies your selections to the selected services.
