- Specify the maximum number of these indexes to limit the total amount of logs stored.
- Specify the appender class in prlogging.xml in addition to the parameters included, for example:
<appender name="PEGA" class="com.pega.pegarules.priv.util.RollingFileAppenderPega">
<param name="MaxBackupIndex" value="9"/>
<param name="MaxFileSize" value="100MB" />
<param name="FileNamePattern" value="'@{web.tmpdir}/PegaRULES-'yyyy-MMM-dd'.log'"/>
<layout class="com.pega.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%20.20t] [%10.10X{pegathread}] [%20.20X{app}] (%30.30c{3}) %-5p %X{stack} %X{userid} - %m%n"/>
