This is an absolutely fantastic piece of software. It's easy to use, detailed and comprehensive.

At present I use it to monitor 16 servers, using several services (ping, http, etc.).

Testing servers via http is essential for me, since most servers would still ping after the webserver has crashed.

The ability to detect changes on the page is fantastic to: it allows me to detect mySQL errors in forums and dynamic sites.

Above all, the support is excellent. I've gotten in touch with Dejal many times with feature requests and (little) bug reports and they have always replied instantly, fix anything that needed fixing and trying to integrate the feature requests into the next release.

Top top it all,my PC friends are jealous when they see it! :-)
