asterisk users - Jan 2008 - Asterisk and MRTG, a little help please...

Hi All,

After reading the sparse info and attempting to get this running, I'm
unsuccessful and could use some guidance.

I already have a MRTG server up and running serving hundreds of router
interface graphs.  I would like to add SIP/IAX channel graphs for all
our asterisk servers.  I'm running asterisk 1.2 and MRTG 2.4.17.  I
tried the script from http://karlsbakk.net/asterisk/ but get errors
that MRTG does not recognize the first few lines, so I think I'm
running into MRTG version compatibility issues.

Can anyone send me the MRTG scripts that may work with this setup?

Thanks.

I have the exact same script from that web page and it runs fine on 
Asterisk 1.2 and MRTG 2.9.29 (default RH ES3.0 install).  I also have 
other servers on RH9 and MRTG 2.10.13 running without issue as well.   
What errors are you getting?

JR,
  That script runs fine. You should be able to run it first manually, if so 
please copy and paste the error.

Thanks,

Alejandro,

Unknown option: h
Unknown option: 1
Unknown option: 2
ERROR: Line 3 (use strict;) in CFG file (10.10.14.102.cfg)  does not make sense

I named the script file the IP address of the server.cfg instead of
asterisk-mrtg.

I call the script from the command line:

# env LANG=C /usr/bin/mrtg 10.10.14.102.cfg -h 10.10.14.102 -1 SIP -2 IAX2

The problem is that is not how its supposed to work.  The file is just a 
script that you need to run from withing a regular mrtg.cfg file. 
So first you build a regular mrtg.cfg file and test it out with 
something you are used to like Ethernet Traffic or whatever.  Then you 
add something like this at the bottom:

Title[servername]: Server title
PageTop[servername]: <h1>servername.domain.com</h1>
Target[servername]: `/usr/local/bin/asterisk-mrtg -h 
servername.domain.com -1 SIP -2 IAX2`
Options[servername]: gauge,integer
MaxBytes[servername]: 90
YLegend[servername]: Active channels

...You see the Target Line...Thats where the perl script from 
http://karlsbakk.net/asterisk/ goes.  It is not an MRTG config file as 
you have tried to use it.

I can see the script log into the manager interface on the asterisk
server at 10.10.14.102, and there are active SIP channels during
script execution.

Any ideas?

Thanks.

I run the script without using mrtg but I don't get any reply:

mrtg:# /var/mrtg/asterisk-mrtg -h [ipaddress] -u [user] -p [pass] -1 SIP -2 IAX2
mrtg:#

I can see the script log into the manager on the asterisk server, but
doesn't return any figures.  i haven't modified anything in the
script.  I'm wondering if the script is OK and maybe Asterisk manager
is not setup correctly or asterisk is not returning proper value.
Here is what I have configured in manager.conf:

[general]
enabled = yes
port = 5038
bindaddr = 0.0.0.0

[user]
secret = pass
deny=0.0.0.0/0.0.0.0
permit=[subnet of mrtg server]
read = system,call,log,verbose,command,agent,user

Thanks.
