There are many server monitoring services out there, but not many have ways for you to easily take in and read that information on your own. One of the few that do is WebSitePulse. They provide a Firefox addon that will give you a brain dead simple way of keeping a watchful eye over your own domains.

Here is a little more about the extension from the developers:

The WebSitePulse Current Status extension provides an easy way to keep an eye in real-time on the status of your servers, websites and web applications when you are using the WebSitePulse monitoring service.

The WebSitePulse extension is broken off into two components. The sidebar will display all targets and their current status. To get more details, all you have to do is click on the name of the target in question.

At the bottom it will also give you a counter telling you when was the last time it was refreshed.

The second component would be the status bar icon which indicates if everything is alright. Here you pretty much play red light, green light. Red is bad and green, well… green is good. You can then right click the status bar icon to customize the extension’s settings.

You will need to also login to WebSitePulse.com and create a free account to use this tool. This current status addon for Firefox does a good job at doing real time status tracking. If you are interested in keeping a watchful eye over your server, it might be worth checking out.
