Do you need generate alerts? Or provide trending information to measure performance? I said mrtg or rrd because you can create graphs based on the ping repsonse time & packet loss between the datacenters, you could also create a graph showing how long it takes to transfere a file to remote site. Basic mrtg and a few simple scripts and a webserver. If you need something that alerts you with e-mail/pages, then nagios, but you'll spend a lot of time in setup and trying to export the nagios checks to into a someting that makes pretty graphs if you need that. I thought the Internap FCP is only for bgp setups, also it doesn't provide the informatoin you're gonna want, at least not that I can tell yet.. :) Ashe Canvar <acanvar@gmail.com> wrote: 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. On 3/28/06, Josh Cheney wrote:
I have had a decent amount of success with Nagios. It is not trivial to setup, but once it is up and running, it has always handled our dependencies and such very well. Additionally, because it calls external programs to do the checks, it is pretty simple to write a script that measures whatever value you would like to monitor. As I said before, it is a pain to set up initially, but after getting it set up, I couldn't be happier with it.

Hi All,
I want a simple backbone monitor for my 5 datacenters. My "backbone" consists of redundant IPSEC/GRE tunnnels.
At the very least I want to ping, traceroute and transfer a small file every few minutes over all IPSEC links. I am sure there are products that do this already, but I am having a hard time finding any.
The display format should be noc-friendly. A basic grid with green/red status indicators at the least. Geographical maps a plus.
Do most of you use a home grown tool for this monitoring and alerting ?
Regards, Ashe
