Alternative Log Rotation Triggers
WildFly allows a rotating file handler to be defined in other ways as well. You can configure it to allow a specified number of log files to be retained that are of a specific age.
A periodic rotating file handler can be used to rotate/renew the log file at a specified frequency as defined by the <suffix> element shown below.
The following example illustrates the configuration for a daily Change log rotation:
<periodic-rotating-file-handler name="INSIGHT_DATA_CHANGE_FILE">
<file relative-to="jboss.server.log.dir" path="insight-data-changes.log"/>
<formatter>
<pattern-formatter pattern="%d{HH:mm:ss,SSS} %s%E%n"/>
</formatter>
<suffix value=".yyyy.MM.dd"/>
<append value="true"/>
</periodic-rotating-file-handler>
The configuration can be changed to rotate the log file hourly:
<suffix value=".yyyy.MM.dd.HH"/>
