RE: Backbone Monitoring Tools
A few more comments. I found a link to snmp management for ospf in an archive message: http://www.cisco.com/en/US/tech/tk869/tk769/technologies_white_paper09186a00 801177ff.shtml. That may yield you the info you need for monitoring links and/or routes. >From my other message, if you collect 1) and 3) with cricket, you can extract RTR and bandwidth data with perl from cricket's config file. I took a bit of code reverse engineering, but I managed to get some mod_perl code going to do such a thing, so it can be done. If you pull out the appropriate interface stats, you'd be able to generate your grid for 1) and 3). -----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.
