Though it is not clear whether you are talking about alert dialogs or bootstrap like messages, I think lastAlert can help you out.
http://sahipro.com/docs is really handy. It provides you a lot of information. Check link http://sahipro.com/docs/sahi-apis/javascript-dialogs.html#_lastAlert - _lastAlert gives you the messages. Also, doc specifies what version of Sahi supports a particular API.
