Giraffe   
by Jobro Software   

Giraffe is a powerful, but still very easy to use, monitoring tool for the .NET Framework. Giraffe can monitor nodes (computers), processes, directories, files and Web (sites or pages).
If anything goes wrong alarms will be generated and these can be forwarded via e-mail. Local or remote doesn't make any difference. Giraffe also includes some tools useful for system monitoring, such as ping, ns lookup, remote process viewer and even a simple send mail tool.
