Per thread CPU statistics in Linux

Question

I want to report the amount of CPU time used per thread in a server process (written in C/C++ on Linux). I can't find the equivalent of GetThreadTimes() on Windows, but that's what I'm looking for.

Can anyone point me in the right direction?

Answer 1

getrusage(2) with RUSAGE_THREAD. From the man page:

int getrusage(int who, struct rusage *usage);

getrusage() returns resource usage measures for who, which can be one of the following:

[...]

        RUSAGE_THREAD (since Linux 2.6.26)
          Return resource usage statistics for the calling thread.
