RE: Backbone Monitoring Tools

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 Check the archives around 2006/02/06.
John Kristoff has an integrity tool at
(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:  Maybe use
Netmap to plot RTR values from 1) rather than the standard bandwidth values

Thanks for the quick responses. Perhaps I should have been more explicit.

I already use "remstats"
( 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

 2. actively detect routing changes / failover to redundant paths using
     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

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 ;)
