Multicast Network Monitoring
Curious if anyone has any experience with tools specifically for monitoring multicast. Finds where the trees are, paths they are on, tracks all senders/receivers per group, handles PIM-SM, RPs, MSDP, MDT Tunnels over MPLS VPN, etc. Such as Cisco Multicast Manager, EMC Ionix Multicast Manager, CA Spectrum? The good and the bad? Worth the effort/investment? Thanks
Interesting question, I'd like to know more about this myself. I'm so used to monitoring SNMP-based devices, never really thought about multi-casts and being able to see the pattern/tree....

Shameless plug, I once developed a tool which was called multicast weathermap. You can see what remains of it here: http://netmon.grnet.gr/multicast-map.shtml (hover over the nodes and the links and you can see various useful info) (you can see the tree of a specific group by selecting from the drop down list at the bottom) and the presentation here http://tnc2004.terena.org/programme/presentations/show2c2c.html?pres_id=47 Since I too myself am into multicast, I intended to incorporate into it everything needed to know everything. But eventually it was left as it is. Apart from that, the NNM advanced used to have a multicast plugin, and it was fairly usable. You could take a look at it probably, but I don't know whether it can handle those MPLS cases you mention. Lastly, those guys at Poznan used to work on a tool called Muvi http://muvi.man.poznan.pl/ You may want to take a look, although I fear it too has been abandoned. Best Regards, Athanasios

Wow that looks great! The URL has an extra "dot" before the SHTML though when you click on it. Easy fix though. Are there no commercial applications for this kind of monitoring? I see your graphs are powered by MRTG. =) Date: Tue, 20 Jul 2010 17:39:17 +0300 Subject: Re: Multicast Network Monitoring From: aduitsis@gmail.com To: brandon.kim@brandontek.com CC: nanog@nanog.org On Tue, Jul 20, 2010 at 4:11 PM, Brandon Kim <brandon.kim@brandontek.com> wrote: Interesting question, I'd like to know more about this myself.

9 Copies here. The headers seem to show a bit of bouncing around inside cisco.com

Maybe they are having issues with their multicast mail routing protocol. Regards Marshall

Or.. perhaps someone over there just turned on smrp routing ? You know.. SMRP ( Sadistic Mail Replication Protocol ) <g> -- -JH

I was wondering what was going on. Kinda tired of seeing my own emails over and over!!!!

I've never seen or used those vendor-specific tools so I can't comment on them. IP multicast can be extremely complex. I'd be interested in hearing if they are any good and what is good about them if so. There have been a handful of community built tools over the years, but nothing as I recall is very comprehensive. What is available now tends to be a defunct research project or simply no longer supported. CAIDA has a small list of some older tools here: <http://www.caida.org/tools/taxonomy/multicast.xml> Marshall Eubanks had one of the best global views of IP multicast, but it too does not appear to be supported any longer: <http://www.multicasttech.com/status/> I had a very cheesey SNMP-based cli tool that grabbed some numbers of useful IP multicast-related OIDs that probably still works: <http://aharp.ittns.northwestern.edu/software/mcastsum> There were a couple of multicast beacon projects, which was a useful way to see how others view your IP multicast connectivity and vice versa. Doesn't look like those are running any longer I'm afraid. I've thought about reincarnating some things I've done or building on some prior work, but there seems to be so little call for IP multicast tools that I haven't been able to justify the time investment. I'd be interested in hearing if there are lots of folks now clamoring for something. John
