Below is the details on apache logging framework.

Sample Logging File :

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = <filename>.txt
1catalina.org.apache.juli.FileHandler.bufferSize = 1024
1catalina.org.apache.juli.FileHandler.rotatable = true

Properties :
The following configuration properties are available:
directory – The directory where to create the log file. If the path is not absolute, it is relative to the current working directory of the application. The Apache Tomcat configuration files usually specify an absolute path for this property, ${catalina.base}/logs Default value: logs

rotatable – If true, the log file will be rotated on the first write past midnight and the filename will be {prefix}{date}{suffix}, where date is yyyy-MM-dd. If false, the file will not be rotated and the filename will be {prefix}{suffix}. Default value: true

prefix – The leading part of the log file name.

suffix – The trailing part of the log file name. Default value: .log

bufferSize – Configures buffering. The value of 0 uses system default buffering (typically an 8K buffer will be used). A value of <0 forces a writer flush upon each log write. A value >0 uses a BufferedOutputStream with the defined value but note that the system default buffering will also be applied. Default value: -1

encoding – Character set used by the log file. Default value: empty string, which means to use the system default character set.

level – The level threshold for this Handler. See the java.util.logging.Level class for the possible levels. Default value: ALL

filter – The java.util.logging.Filter implementation class name for this Handler. Default value: unset

formatter – The java.util.logging.Formatter implementation class name for this Handler. Default value: java.util.logging.SimpleFormatter
