While at the end of Brunel or DaVinci, the execution time of each individual algorithm is displayed in the TimingAuditor, this is not true for tools. To monitor the time for tools (it also works for algorithms), the follwing has to be implemented.

You can't just switch on the TimingAuditor for tools. Instead you have to add some lines to your tool. In the myTool.h -file:

#include "GaudiKernel/Chrono.h"

In the myTool.cpp-file, in the method you want to monitor the time:

Chrono chrono( chronoSvc(),name()+"::myMethod(parameters)" ); 

This will generate at the end of the job some lines like:

*****Chrono*****     INFO ****************************************************************************************************
