Re: [asterisk-users] Peak number of calls?

my $username should be a user in the asterisk management file.
my $password should be the password for that account.

So this is OK for busy sites where a few calls either way won't be noticed, but I'm dealing with relatively low call volumes of 1-2 a minute, with very occasional bursts to (maybe, I don't know yet!) 4-6 simultaneous calls. (I have a customer who has 4 ISDN2e ports; 8 channels) and they want to know if they can lose one port and save some money) I'm working on something slightly better that will poll it more often, but still provide an mrtg interface. I'll post details here, but it's not that high a priority right now.

No, the CDRs would be where that information is stored, if anywhere. This is actually sort of easy. You simply have every call pass through a context in which you assign the call to a group, then either do a NoOp echoing the group count or a user event doing the same, then either programatically or grep search your logs for the output or have a script monitoring the AMI watch for the user event and write the number in a data base. Of these two I personally do the second option because then I can just do a max() function on that database field to get the maximum calls for any time range I specify. Oh and just a note, never just say no because you don't know, in this instance you would say, I think your best bet is the CDR's. Just a tip. The key phrase in the original post was has had, indicating past behavior, not future behavior. Yes, you can do all sorts of things in the dialplan to get that information into a logfile, but you cannot retroactively do those things. The only place that information can be had are the CDRs, so I will stick with my original assessment. Yes, nice to know what happened in the past, but also nice to know what happens in the future, so I'm not overly hung up about how. (And the CDRs aren't in a database either - just flat file on my devices) I did actually think of adding in some diaplan stuff to keep counts, but I've now got a skeleton and a good idea if something that'll keep me happy. Basically 2 parts - one which polls the system via the manager inteface every few seconds to count calls, and another which interfaces to mrtg. I didn't really think of this initially as for a long time my units did have perl, (which mrtg needs) but I've managed to squeeze in enough perl to run other things now, so off I go.
