Change Roll Frequency of the Audit Log

Audit records are written to the log file /var/log/knox/gateway-audit.log and by default roll monthly. When the log rolls, the date that it rolled is appended to the end of the current log file and a new one is created.

1. Open the $gatewaydir/conf/gateway-log4j.properties file in a text editor.
2. Change the log4j.appender.auditfile.DatePattern as follows: log4j.appender.auditfile.DatePattern = $interval.

   Where $interval is one of the following:

   Setting	Description
   yyyy-MM	Rollover at the beginning of each month
   yyyy-ww	Rollover at the first day of each week. The first day of the week depends on the locale.
   yyyy-MM-dd	Rollover at midnight each day.
   yyyy-MM-dd-a	Rollover at midnight and midday of each day.
   yyyy-MM-dd-HH	Rollover at the top of every hour.
   yyyy-MM-dd-HH-mm	Rollover at the beginning of every minute.

   	Tip
   	For more examples, see “Apache log4j: Class DailyRollingFileAppender”.

3. Save the file.
4. Restart the gateway: cd $gateway bin/gateway.sh stop bin/gateway.sh start.
