Kernel Tracing With LTTng On Ubuntu Maverick

Posted by kdawson on Saturday November 13, 2010 @03:25AM from the truth-of-kernel dept.

francis-giraldeau writes "Linux Tracing Toolkit (LTTng) provides high-performance kernel tracing for Linux. This is the killer app for system level debugging and performance tuning. It's now easier than ever to install, with packages released for Ubuntu Maverick. The short introduction to kernel tracing shows how to interpret a simple kernel trace and relate it to strace. I would like to ask Slashdot readers what they would expect as features for a kernel tracing analysis tool, because I'm starting my PhD on this topic and looking for ideas. Also, I wonder why LTTng is not mainline yet. Will Linus Torvalds see the light in 2011?"

The reason is that I would like to make my research useful for tracing users, and I think the best way to do it is to ask people what they really need. I will give credits to those how helped my, why not? ;-)

Not that much point having a tracing tool if an inexperienced admin cannot safely use it on a live system which has a problem.
A problem already solved with DTrace on Solaris http://docs.sun.com/app/docs/doc/817-6223
