moveit benchmark log, where is it?

edit

Hello!

I am trying to run some benchmarks with moveit and the rviz plugin, following this tutorial: http://moveit.ros.org/wiki/Benchmarking

The benchmark seems to run without problems, except that I am not able to find the log file to see the results.

In the tutorial it is stated this, about the configuration file parameters:

output (optional) Location for saving computed data in *.log format. "1.log" will automatically be appended to the file name. The default output location is in in your ~/.ros folder.

but I can't find the log file in that folder... Maybe it's a bug? Where do I have to search for it?

Thank you in advance!
