Function module/Webservice for Sytem status overview widget

Hi,

We want to create a "System status overview" - widget, which can show very briefly an overview of which systems are up an which are down (+ some additional backgroundinfo).

(Instead of communicating system statusses via e-mail)

Therefore we are looking for a function module/webservice which provides status info of all systems linked to Solution Manager. Does anybody knows about a standard functionality which provides this information, or does an application lik that already exists?

Thanks in advance for your replies.

Cheers,

Sander
