Hello,<br>
<br>
sounds useful for live monitoring - is it ok to include it in our
repository, kind of in utils folder?<br></div></blockquote><div><br></div><div>No problem.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div bgcolor="#ffffff" text="#000000">

The last version is able to print the summary of allocated
fragments, a matter of mem_summary value:<br>

<br>
Have you tried it?<br></div></blockquote><div><br></div><div>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. </div>
<div><br></div><div>p.s Please note the program I sent is obv. dependent on the format of the logfile because of the regex's in there.</div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

<div class="gmail_quote">Hi All,
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>A little info:</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Here is an example of the output:</div>
