How can I purge de table [Sawmill_Wowza_logs]?

In the serveur Database, I want to purge de [[Sawmill_Wowza_logs] table.

How can I do ?

The log4j appender being used by Wowza is not able to automatically delete older log files @Pat Mil, but it creates a log file set for each day. You can create a script that can be scheduled to run once per day and have that script delete log files that are older than x days.

The following article explain how to adjust log rolling by time or by size:
