search for: getrusag

I'm failing to understand how getrusage() works, which is a bit perplexing, because it doesn't seem like it would be terribly complicated. I've attached the code. My aim is to verify that I can use getrusage() to do (admittedly crude) instrumentation of which functions in my program are allocating lots of memory[1]. So I figu...

The builtin entropy gathering code in OpenSSH 2.1.1p1 tries to use getrusage() if it's available. This function is available on Solaris 2.5.1, but you must have root permissions to run it. However, configure.in uses only AC_CHECK_FUNCS() to look for getrusage, and this only tests for a successful link. For this function you need to do a more thorough check and actua...

I'm using a call to the resource module's getrusage method. On openSUSE this works, on CentOS [python26-2.6.5-3.el5] it 'works' but just returns zeros for the memory utilization values. resource.getrusage(resource.RUSAGE_SELF).ru_maxrss openSUSE: returns 5512 CentOS: returns 0 Anyone know what condition causes this? Or is there a bet...

...make sense and have observium plot two data sources with different orders of magnitudes right into one graph. So I'd like to ask for your valuable recommendations as for: - What kind of data should be graphed? Global stats or on a per domain level? - What data types to graph? (e.g. stats, getrusage, io, storage, auth check https://wiki2.dovecot.org/Statistics#line-65 for details) - What values should be combined into a single graph? - How often would you reset stats (cronjob calling doveadm stats reset)? Thanks Thomas [1]: http://www.observium.org/ [2]: http://docs.observium.org/apps/...

Seems I had forgotten that you can use src/lib/restrict.h, in particular, restrict_get_process_size() to figure out the limit. You can combine this with getrusage to find out current usage.
