Re: [Serusers] How to build in SER modules statically for profiling?

Your post belongs to serdev. Here is a serdev post from Hendrik Scholz some time back. g-) Hi! I'm about to profile our SER installation and since profiling doesn't run out of the box here's a rough guide: - you'll need to build SER from sources, thus get sources, apply your patches and so on - before compilation get this patch (for CVS HEAD): http://dump.wormulon.net/patches/ser-profiling.diff Call $ patch -p0 < ser-profiling.diff from the SER base directory. What it does it invoking monstartup() in each child process since the profiling information get lost when fork()ing. I added all childs including timer and fifoserver. If you are only interested in certain worker processes you can cut down the resource impact by selectively activating profiling. - enable profiling in Makefile.defs - Set both -DPROFILING and PROFILE=-pg - compile and deploy as usual - Before starting SER using your standard init script you need to set an environment variable that acts as a prefix to all profiling data files. If you don't set it you'll only get one file for the main process. # export GMON_OUT_PREFIX=testrun The gmon files will be named testrun.<PID> with the PID matching $ serctl fifo ps SER may change the current working directory and drop privileges on the way therefore I suggest you invoke the init script from the SER working directory (-w option) so you'll end up with all files in one place. - Run SER for a while. Not all gmon files will show up immediately, though. - You should now be able to get per-process statistics using $ gprof /usr/sbin/ser testrun.<PID> - If cummulative statistics are what you are looking for use $ gprof -s /usr/sbin/ser testrun.* to create a new gmon.out which contains statistics over all processes. I have yet to fully analyze the results.
