Internals of systemtap

I want to know what actually happens internally when the event written in the tap file occurs and how it is handled?

Solution

  • You should read the documents presented at the end of the SystemTap Documentation page, especially the Locating System Problems Using Dynamic Instrumentation OLS paper, to know a bit more about the internals.

    The Introduction to KProbes article at LWN is worth a read too.
