Hi Manju,
You can have a look into this discussion answer regarding your query which might help you to proceed further. The referred discussion explained with the tomcat 6.0 logging documentation reference, as you are using tomcat 8.5 sharing the corresponding logging documentation over here.
Hope this might help you to proceed further.

The following steps describe configuring log4j to output Tomcat's internal logging.
The following steps describe configuring log4j to output Tomcat's internal logging.
- Create a file called log4j.properties with the following content and save it into $CATALINA_BASE/lib
- log4j.rootLogger = INFO, CATALINA
- # Define all the appenders
- log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina
- log4j.appender.CATALINA.Append = true
- log4j.appender.CATALINA.Encoding = UTF-8
- # Roll-over the log once per day
- log4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd'.log'
- log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout
- log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
- log4j.appender.LOCALHOST = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.LOCALHOST.File = ${catalina.base}/logs/localhost
- log4j.appender.LOCALHOST.Append = true
- log4j.appender.LOCALHOST.Encoding = UTF-8
- log4j.appender.LOCALHOST.DatePattern = '.'yyyy-MM-dd'.log'
- log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayout
- log4j.appender.LOCALHOST.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
- log4j.appender.MANAGER = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.MANAGER.File = ${catalina.base}/logs/manager
- log4j.appender.MANAGER.Append = true
- log4j.appender.MANAGER.Encoding = UTF-8
- log4j.appender.MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
- log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayout
- log4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
- log4j.appender.HOST-MANAGER = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.HOST-MANAGER.File = ${catalina.base}/logs/host-manager
- log4j.appender.HOST-MANAGER.Append = true
- log4j.appender.HOST-MANAGER.Encoding = UTF-8
- log4j.appender.HOST-MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
- log4j.appender.HOST-MANAGER.layout = org.apache.log4j.PatternLayout
- log4j.appender.HOST-MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
- log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender
- log4j.appender.CONSOLE.Encoding = UTF-8
- log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout
- log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
- # Configure which loggers log to which appenders
- log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] = INFO, LOCALHOST
- log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager] =\
- INFO, MANAGER
- log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager] =\
- INFO, HOST-MANAGER
With the help of DailyRollingFileAppender you can roll the logs daily .
