In PI System Management Tools, under the Database Security plugin, the description of the PITUNING table is:
"Controls access to Timeout parameters and the Firewall"
"Timeout parameters" is the old name for "tuning parameters", I'm guessing from the days when the tuning parameters stored mostly connection timeout times. New PI administrators will not know what a timeout parameter is. Please change the description of PITUNING to:
"Controls access to tuning parameters and the Firewall"
