Subject: [ltt-dev] limiting LTTng to a certain set of cores
Date: Wed, 11 Feb 2009 09:32:56 +0000	[thread overview]
Message-ID: <v4vdrhnws7.fsf@swi-aim.swindon.wrsec.fr> (raw)


Is there an easy way to limit LTTng to trace a specified set of cores
only?  I ask because in some 64+ core systems the data set collected
becomes too large for analysis and the tasks to be analyzed are always
bound to certain cores (using affinity).

I'm anticipating that this would require changes to LTTng - what I would
like to know is how invasive those changes would need to be.

Thanks,
Andy.
