If stats are reset it means it is unable to read asternic data. You must be sure the asterniclog service from asternic (licensed or not) is running:
service asterniclog status
If its not running, start it:
service asterniclog start
Another thing to check could be mysql permissions, check the Full Wallboard installation guide , at the very top it shows some permissions you might need to add to mysql.
