Very Little Data from Google SDK Connector

I have managed to get the Google SDK Admin connector to connect to my good instance but I'm getting very little data. I have about 1000 users and for 'Customer Usage' I get 1 line per day with a parameter value of (for instance ) "105" or "209", and lots of empty Columns. I believe the delegations are correct, is there potentially some logging I need to turn on in google ?
