There are two kinds of tests you can perform with ServerWatcher. You can test if a secure or insecure web page contains a specific piece of content or you can just ping the server to see if its hardware is still up.
Testing Web Pages
Click the Green plus on the Servers tab to add a new server. Where it says "Name to Display" you'll want to enter a simple descriptive display name for the server. This will show up in the list, e-mails, and the status web page. Put the url of the web page you wish to test into the url field. In the Match String field you want to enter any piece of text exactly as it will appear in the source of the web page. If your pages are dynamically generated this must be something that will always be on the page. The match string is intentionally case sensitive.
Urls should look like this: http://www.myserver.com or https://www.myserver.com
Pinging a Server
Pinging a box will let you know if it is on and connected to the net. Sometimes it is useful to Test a web page and ping the same server because it is not uncommon for server software to go down while the hardware stays up. If you test both you will know what the situation is.
Click the Green plus on the Servers tab to add a new server. Put the url of the web page you wish to test into the url field. Ignore the match string.
Ping urls should look like this ping://www.myserver.com
This should work on any system that has ping available from the command line. If you have problems with ping on your system please file a report a bug and indicate what operating system you are on.
Removing a server
To remove a server simply select it and click on the red minus button.
