OVCirrus client traffic log retention

Can I know the application log of client traffic can be store in OVCirrus for a period of 30 days or more?

Assuming you refer to Application (Deep Packet Iinspection) discovery : it is stored for a period covering the last 30 days and allows you to display information for a specific time frame : 7-day period, 24 hours period, las 24 hours or last 7days.
