Configuring Log Controllers 
This procedure allows you to configure at runtime the severity of:
certain log controllers
the whole system tree
a certain system instance
Before changing the severity of a log controller, bare in mind that:
If you change the severity of a log controller on a system (template) level, the new severity will be valid on all instances for this log controller. That is, the severity change is on system level.
If you change the severity of a log controller for a particular instance, and this severity is different than the ones on the other instances, the change will be valid only for the particular instance.
Note
You can still set a uniform system severity as either setting such for the tree or equalizing the instance severities in the Per Instance Configuration tab.
