<div>Do you need generate alerts? Or provide trending information to measure performance?</div> <div> </div> <div>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. </div> <div> </div> <div>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.</div> <div> </div> <div>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.. :)</div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><BR><BR><B><I>Ashe Canvar <firstname.lastname@example.org>
