I am only interested in a single event. I presume that vtsarun captures all events, but I can't find any way of telling it to only capture the one I'm interested in. I'd like to use it over a long-running test, and given that it would produce about 1.6GB of data per hour, that might be a problem.
Obviously I could change the sampling interval, but then there would be less information in the results. It might be possible to manually set collection off using the -ec parameter, but specifying that for each event other than the one I'm interested in is unpleasant.
Is it possible to make vtsarun only record data for a specific event?
