I use a package called mrtg - available for most platforms I believe.
The summary page is hand-rolled html which grabs the images from each of the mrtg-generated pages.
To figure out what interface number to use in the mrtg.cfg file, I use a linux command-line tool called snmpwalk which will dump the snmp table of the cisco router - do something like this:
[root at monitor hecnet]# snmpwalk -v1 -c hecnet hub.platinum.net | grep ifDescr
IF-MIB::ifDescr.1 = STRING: Ethernet0/0
IF-MIB::ifDescr.2 = STRING: Ethernet0/1
IF-MIB::ifDescr.3 = STRING: Null0
IF-MIB::ifDescr.4 = STRING: Tunnel0
IF-MIB::ifDescr.5 = STRING: Tunnel50
IF-MIB::ifDescr.6 = STRING: Tunnel52
IF-MIB::ifDescr.7 = STRING: Tunnel53
IF-MIB::ifDescr.8 = STRING: Tunnel54
IF-MIB::ifDescr.9 = STRING: Tunnel55
[root at monitor hecnet]#
This shows you that interface 0 is the ethernet port, interface 5 is tunnel50, etc. You need to enable snmp on your cisco with:
snmp-server community hecnet RO
(choose your own community string - these were just examples).

Loads without complaining now. Thanks!

Ooops, sorry about that. Fixed. Sending new config.

Right. Due to the nature of the way I changed things I broke that. :)

Correction - tunnel destination should be an IP address, not "1". Every destination is wrong in the last update pushed.

Brian,
What's the status of your script? I'm using your auto generated config, and it's working great for me. However, I'm not seeing any other tunnels come up other than the one to you, leading me to suspect that no-one else has started using it yet. Is everyone else ready to go?
I'm still waiting on Peter, but I can start declaring this ready I think.
I just rewrote it slightly to use a db instead of a csv file. This will allow some neat features in the future, including allowing you all to update you info (change stuff, add end-point routers, etc) yourself via a web page.
It now also more elegantly handles dynamic IP addresses and makes it easier for me to check those.
There is still more work to do, but I think it's "good enough" for now. :)

Interesting, that is the correct one. The VM must've been glitching then. Updating the host VM now to see if I can resolve the 40-60% packet loss issue...

Good news!
If anyone's interested, here's a MRTG summary page (with clickable images) for the traffic on each tunnel at my end. In case anyone's interested in how much chatter a fully-meshed environment produces.
I'd love to know how you configured this. I like having useless charts generated and then emailed to me if possible. ;)
