If not set, a component’s trace threshold level is inherited from its parent, or the default trace level if the component does not have a parent. A component's parent is the component that appears to the left of it in component-name. For example, if component-name is mf.rts.subsystem, mf is the parent of rts, and rts is the parent of subsystem.
Use mftrace.level.component to specify the level of tracing that is to be performed by the specified component and any components that inherit from it. You can specify multiple mftrace.level.component entries in the configuration file, but an entry that specifies a tracing level for a component that has previously been set overrides the previous setting.
To set the WARN tracing threshold level for the mf.rts component and the DEBUG tracing threshold level for all other components:
... mftrace.level=debug mftrace.level.mf.rts=warn ...
