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 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 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ashe Canvar Sent: Tuesday, March 28, 2006 20:07 To: [email protected] 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.
