1. Cricket with Acktomic tools to monitor Cisco SLA/SAA/RTR values
2. ospf snmp traps to snmptrapd? I think somewhere in the archives someone
did some perl scripting to watch ospf stuff. OSPF has some mibs that can be
used for data gathering. Ed Ravin had an add-on for
http://linux.kernel.org/software/mon/. Check the archives around 2006/02/06.
John Kristoff has an integrity tool at http://ntgrd.depaul.edu/software/
(may not be what you look for). Check the archives around 2006/01/18. If
nothing else, they may show you how to get at the OSPF stuff you want.
3. is netmap what you are describing:
http://www.it.teithe.gr/~v13/netmap/img/netmap-1.3.0-1.png? Maybe use
Netmap to plot RTR values from 1) rather than the standard bandwidth values

Subject: Re: Backbone Monitoring Tools
Thanks for the quick responses. Perhaps I should have been more explicit.
I already use "remstats"
(http://remstats.sourceforge.net/release/index.html) for interface b/w
monitoring. I have worked with nagios and openview int he past.
I have an ospf based network. The specific monitoring problem I am trying to
solve is :
1. actively test the currently active path for packet loss and transfer
i.e. draw a latency grid between every datacenter and every other
datacenter
2. actively detect routing changes / failover to redundant paths using
traceroutes
i.e. alert if SFO->CHG->NYC changes to SFO->LXE->HOU->NYC
( link state protocols suck as far as testing backup paths go)
3. actively transfer a fixed file
i.e. draw a datarate grid between every datacenter and every other
datacenter
So, I am not looking for a generic graphing/alerting NMS. Does anyone use a
specific tool that is capable of doing this ?
I am in a buy vs. build debate with my boss ;)
Regards,
Ashe.
