Is there any way to find-out the peak number of calls that an asterisk system has had? Not the total number of calls, but the maximum number of simultaneous calls. I know I can porobably go through the CDR logs and look for calls which have overlapped in time, but I'm wondering if there's some counter somewhere I could access... (I'm looking for evidence for an ISDN client who wants to know if he's spent too much on the number of ISDN lines he has installed!) Cheers, Gordon

I use MRTG in a lot of applications, so this is worthy of a look. It only samples every 5 minutes though, so has the potential to miss things, although this (and the crude shell-script suggested by Steve Edwards has presented me with an idea to use the manager interface to sample it a bit more often and keep a count. Thanks! Gordon

I use mrtg,
I call this from MRTG: `/usr/local/groundwork/nagios/libexec/asterisk-mrtg.pl -1
Zap -2 SIP`
Here is my asterisk-mrtg.pl: (note, I have tweaked this, but I do not know where
I had gotten my original reference)

-----------
my $username should be a user in the asterisk management file.
my $password should be the password for that account.
This gives me this output:

5 Zap channels in use
1 Zap channels in use
0 Zap channels in use
