Hey Merlin,
Thanks for sharing this code! It will be helpful for a monitoring script i need for doing some sysadmin tasks!

It would be great if you publish it on a blog!

Just thought one or two of you may be interested on how to get some BIOS and O/S level details on a Windows platform.  To do this you will need to use the JACOB interface to COM, that allows Java to interact with com/dcom components.  In this case, to access the WMI Scripting feature set.

Note: JACOB is installed with Groovy when using the Windows distribution (not the zip or scripted installer versions). This is cribbed from the excellent example already in the Groovy distribution.


Now to figure how to do similar for Linux (dmidecode + ?) and on VM platforms!

Why? To find some sort of meaningful but ‘unique’ attribute(s) of the server on which the service is running.
