Well I guess you wouldn't want your monitoring tool indexed by Google anyway, right? As soon as you only have JavaScript as the only way for accessing some data it will be harder to index. There are some solutions provided by Google https://developers.google.com/webmasters/ajax-crawling/ but the situation still is not satisfactory.

For my clients it's usually the case that being found well in Google is a major part of their business case. PE makes sure that a basic crawlable version of your website exists with proper titles and tags.
