Hello Michael,
there are more steps to get your requested date. First of all you have to use the XMC database not a NAC database. All data are transmitted and aggregated in XMC.
Here is a excellent article how to connect to the database from
@Martin Flammia (he is here in the HUB, too):
http://www.extremenetworks.guru/extreme-networks-managemet-netsight-access-database-externally/
If you are connected to the database (the correct one is the netsightrpt database for the statistics), you have to check where your data are stored. For that "select * from rpt_statistics" to receive all statistics availably on your system. Please be awary that entries differ from installation to installation.
Search in the output for your statistic. I think the display name is "NAC End-Systems seen last 24 hours "
Take the ID form the first column.
Now you can do an "Select * from rpt_default_day where statisticid =
Have fun.
Best regards
Stephan
