We monitor our upstream provider core routers. Basically, we monitor every physical device between us and them. So, if any device goes down, we can tell where the problem is originating from.<div> </div><div>Secondly, if you have a co-located server outside your network, you can monitor that as well.</div><div> </div><div>Alex <div class="gmail_quote">On Jan 25, 2008 8:54 AM, Giles Coochey < <a href="mailto:gcoochey@sapphire.gi">gcoochey@sapphire.gi</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi List, As part of our Internet Connectivity monitoring I monitor a set of websites on the Internet from a diverse number of locations geographically. There are some issues with this: (a) I have to avoid sites that use Content Delivery Systems such as Akamai, because as we host such boxes ourselves the websites actually load from local servers which we host rather than the intended geographic location. Most large sites such as <a href="http://www.yahoo.com" target="_blank">www.yahoo.com</a> and <a href="http://www.google.com" target="_blank"> www.google.com</a> use these content delivery systems. (b) I have to avoid small sites which often go down due to lack of redundancy in their implementation. (c) I have to avoid sites which might get pretty annoyed that I'm pulling their homepage once every 10-15 minutes just to see if I'm getting good access. I would like to hear from others on the list as to what they do to check Internet Connectivity and whether they do any smart stuff to include multiple connectivity checks as a single service check. What do you do? Thanks Giles ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
