Hello,
sounds useful for live monitoring - is it ok to include it in our
repository, kind of in utils folder?
No problem.
The last version is able to print the summary of allocated fragments, a
matter of mem_summary value:
http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x#mem_summary
Have you tried it?
I havent yet, I am still stuck on Kamailio 1.5 - as we have MANY custom
changes to it, so porting to later versions is quite a task. BUT as you
mentioned the one I did helps me because it is LIVE. I can therefore do
certain activities and effectively monitor what is happening with my memory
in a nice 'at-a-glance' manner.
p.s Please note the program I sent is obv. dependent on the format of the
logfile because of the regex's in there.
Thanks,
Daniel

Hi All,
thought I would give you a small little perl program I quickly hacked up
to help with some memory leaks I was getting. Turns out I was forgetting to
call release_urecord after a get_urecord on the usrloc module. Because I use
Kamailio in DBOnly mode - the memory was never being freed. This little
program helped me to find the source in no time at all. I hope it helps you
too.
A little info:
The program works on the log file. NB you have to have memlog debugging
enabled for this program to do anything useful. Effectively the program
continuously monitors the log file looking for allocs and frees. It tallies
all the fragments in use and gives a report of all the fragments and where
they weer allocated. It also keeps a running counter of bytes used.
Here is an example of the output:
*****************************************************************************************************************************************************
DUMPING ALL UNFREED MEMORY FRAGMENTS (25)

To use - simply untar into a directory and run ./memalyze.pl
Hope it helps
Cheers
Jason
