Analytics with MultiSite Integration

Just want to clarify some general information on using this plugin with multisite. I have network activated the plugin and set all the necessary settings in the network side however over a day has gone by and no data is being populated in any of the sub-sites. Do I need to add the Analytics tracking code to the sub-sites setting panel as well?

Is there anything else I could be doing wrong? I am also using the domain mapping plugin.
