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. 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

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
