Hello,
sounds useful for live monitoring - is it ok to include it in our
repository, kind of in utils folder?
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?
Thanks,
Daniel
