dovecot - Sep 2014 - how to profiling imap process with valgrind

Hi,

I want to profile runtime performance of imap and pop3 processes. There
processes are forked by dovecot master process. I am wondering if there is a way
I can profile these processes with valgrind. I tried "service =
/bin/valgrind /bin/imap" but this did not work.

Thanks,

You could try:

service imap {
  executable = /usr/bin/valgrind --num-callers=50 --leak-check=full -q
<DOVECOT-PATH-PREFIX-HERE>/libexec/dovecot/imap
}

service pop3 {
  executable = /usr/bin/valgrind --num-callers=50 --leak-check=full -q
<DOVECOT-PATH-PREFIX-HERE>/libexec/dovecot/pop3


Fix the paths for valgrind and Dovecot libexec/ to match your system. Depending
on your distribution and library versions you
may also want to add --suppressions for some external libraries. Valgrind output
will be in Dovecot error log.
