How to specify the trace options?

To begin, enable all the available options by copying the .options file from the plugins\your_plugin subdirectory into your \eclipse directory. This will enable all options.
For example:
org.eclipse.cdt.debug.mi.core/debug=true
org.eclipse.cdt.debug.mi.core/flag=true
org.eclipse.cdt.debug.mi.core/filter=SampleAction
