Displaying and Changing Log Settings 

Use

You can change the severity level for single log controllers in the productive system at any time using the VMC Administration (transaction SM53).Choose Log Administration → Log Configuration.

Here you can specify which log messages get recorded by the system. If you display the log messages, you can restrict the number of hits (see Displaying Log Messages).

You can find all the options for setting the VMC log system in the configuration file logging.xml, in subdirectory cfw/conf/vmc_runtime/base (for the configuration delivered by SAP) or in cfw/conf/vmc_runtime/custom (for customer configurations).

Among other things, here you can specify which messages, and in what detail are written to which files. Changes to this configuration should only be made be experienced administrators and only in the custom directory. They only become active when the VMC is started or reset.

Procedure

...

       1.      In the left frame of the VMC administration (SM53) choose Log Administration → Log Configuration.The following screen appears:

       2.      Configure the log settings according to your wishes. You can select any location or category you like and change their severity settings. Any changes and their effects on lower-level nodes are immediately visible in the tree displayed. You can also insert log controllers unknown up to now, by entering the full name in the input field and copying the relevant setting.

Note that if a setting writes too much information to the log and trace files will affect system performance. Restrict the level of severity and activate detailed tracing only for the time of the error search.

Result

The changes you made are effective immediately, but they are not saved – they are valid only until the VM is restarted or reset.
