Does anyone out there have a recommendation for tools that will monitor the quality of VoIP systems? I am looking for jitter and MOS monitoring. I have a custom Nagios plugin that is alerting me if the jitter jumps out of a 20ms but I am looking for a little more detail. I would not be against writing something in Perl for Nagios to do but I don't really know where to start on measuring jitter other than with ICMP pulls and really don't know where to start with doing MOS. Any ideas? Thanks Curt -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20060622/dad430d0/attachment.htm

It is really just a play on the check_icmp plugin. You could accomplish the same thing by doing the following: $USER1$/check_icmp -H $HOSTADDRESS$ -w 80.0,80% -c 100.0,100% -n 1 Where in this example it is an RTA of 80ms or 80% packet loss for a warning and 100ms or 100% packet loss for critical. The perfdata is then passed to perfparse for graphing. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Anthony Rodgers Sent: Thursday, June 22, 2006 2:02 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Quality monitoring Care to share your Nagios plugin?

I haven't tried the scripts yet, but the book "*VoIP Hacks : Tips & Tools for Internet Telephony (Hacks)" (http://www.amazon.com/exec/obidos/tg/detail/-/0596101333/qid=1151018442/sr=2-1/ref=pd_bbs_b_2_1/103-6123898-6212653?v=glance&s=books) has a collection of perl scripts for monitoring network quality, including, IIRC, jitter. I don't know how well the scripts will work with Nagios, but it might be worth checking out. --Mike *> Message: 13 > Date: Thu, 22 Jun 2006 12:53:50 -0400 > From: "Curt Shaffer" <cshaffer@gmail.com> > Subject: [Asterisk-Users] Quality monitoring > To: "'Asterisk Users Mailing List - Non-Commercial Discussion'" > <asterisk-users@lists.digium.com> > Message-ID: <012301c6961c$7121d090$8800550a@acg.arlington.local> > Content-Type: text/plain; charset="us-ascii" > > Does anyone out there have a recommendation for tools that will monitor the > quality of VoIP systems?
