Tracing on Linux

Mar 08, 2011, 20:35 (0 Talkback[s])

"The Linux tracing APIs are a relatively new addition to the kernel and one of the most powerful new features its gained in a long time. Unfortunately the plethora of terms and names for the system can be confusing, so in this follow-up to my previous post on the proc connector and socket filter, I'll take a look at achieving the same result using tracing and hopefully unravel a little of the mystery along the way.

"Rather than write a program along the way, I'll be referring to sample code found in the kernel tree itself so you'll want a checkout. If you're doing any work that touches the kernel further than standard POSIX APIs, I highly recommend this anyway; it's quite readable and once you find your way around, is the quickest way to answer questions."
