Hello,
There is a good amount of content on Connect regarding IT Analyitcs for SEP. I would start with this article:
https://www-secure.symantec.com/connect/articles/installing-and-configuring-it-analytics-71-symantec-endpoint-protection-pack
For more articles specific to IT Analytics for SEP, you can go into the Security community and search for articles and videos under the author 'dprager.'
To answer your question specifically, IT Analytics will need to be hosted by the Symantec Management Platform, which is installed on a separate server. If you have this running in your environment already, you'll simply need to install the SEP content pack.
Hope that helps.
