Analytics data not showing/visible

thank you for your reply Jess,
I can see analytics update through GUI but it's updated once per day as you mention, i read about update statistics every 4 hours? also even if the analytics is updated but video plays in content tab doesn't updated either daily or hourly ? its always 0 even if its list in top content?
also, can you briefly list the update sequence as I can't find a description for each job what it does exactly
e.g. 1. rotate logs
2. /opt/Kaltura/DWH/etlsource/execute/etl_update_dims.sh update the database table 1,2
