What it does? Good question! Let me explain (taken directly from the website):
’…Global Service Monitor is an Azure-based service that extends SCOM 2012 capabilities into the cloud. It allows you to schedule synthetic transactions from geo-distributed locations to monitor availability, performance and reliability
of your externally facing web applications….’
Still not totally clear? Don’t blame you! Let me ‘translate’ it for you in plain ‘French’:
GSM enables one to monitor the company’s most crucial websites from the OUTSIDE. Suppose your company has websites hosted in Europe which are also visited from the US. Wouldn’t it be great to monitor these websites from the US as well? So you REALLY know whether the websites are available from the US as well and responding in a timely manner? And to run synthetic transactions against those websites from the US as well? GSM does just that!
Awesome isn’t it? At MMS 2012 I attended a special closed session about GSM. Really impressive it is.
For now there is a Consumer Preview available through Connect. All you have to do is to sign up and you’ll receive all the required materials for GSM. As far as I know GSM will be GA when SP1 for System Center 2012 is RTM.

As you can see, OM12 isn’t work done but evolution in progress :).
