I need a web server monitoring tool that does the followings: 1. This monitor is set up externally, so that, if the server that runs this web server goes down, it's not affected at all. 2. This monitor checks a certain text on a certain web page so that, if the web application that generates the web page starts misbehaving, I would be notified. 3. This monitor keeps emailing me, uh, ... every 5 minutes, 10 minutes or an hour for hours and days until I fix this problem. So, for example, if I get sick and stay in bed for 3 days, when I come back to work, I would find out about this problem immediately. Can someone recommend me a web server monitoring tool that does all these things?
