Appboard/old/log files

AppBoard/enPortal provides various log files to assist you with monitoring and troubleshooting. This article details the log files that are provided.

AppBoard/enPortal Log Files

Location

AppBoard/enPortal maintains log files primarily in the following location:

• [INSTALL_HOME]/server/logs

Summary

The following table summarizes each log file and the information it provides:

tomcat.log.[day_of_week]	The standard log file for the Tomcat web application container

Rotation

Log file rotation is configured in the config.properties or appboard.properties files under /server/webapps/enportal/WEB-INF/config/, including settings such as the following:

[xml,N]

1. Log cleanup settings

logwatch.error.prefix=${logger.logs.path}/error.log logwatch.error.numberToKeep=7 logwatch.error.compress=true

logwatch.system.prefix=${logger.logs.path}/system.log logwatch.system.numberToKeep=7 logwatch.system.compress=true

logwatch.session.prefix=${logger.logs.path}/session.log logwatch.session.numberToKeep=7 logwatch.session.compress=true

logwatch.ldap.prefix=${logger.logs.path}/ldap.log logwatch.ldap.numberToKeep=7 logwatch.ldap.compress=true

logwatch.access.prefix=${logger.logs.path}/localhost_access_log logwatch.access.numberToKeep=7 logwatch.access.compress=true logwatch.access.skiplast=true

1. Log cleanup settings

logwatch.appBoard.prefix=${logger.logs.path}/appBoard.log logwatch.appBoard.numberToKeep=7 logwatch.appBoard.compress=true

This background job can be used to clean up any files that always have the same prefix. It assumes either the files are names: (<logname>, <logname><suffix1>, <logname><suffix2>) or (<logname><suffix1>, <logname><suffix2>, and so on). In the first case, the one without the suffix is assumed to be the current log, while in the latter a flag “skiplast” is used to not archive/delete the last (in alpha-numeric ordering). This is only used for the tomcat access log.

numberToKeep does not include the current log, and compress will put the old log in a file named the same with ".zip" added. The process runs every 30 minutes to look for old files that need to be processed.

Configuration

The standard log files above are written using the log4j library and can be configured through the enportal/WEB-INF/classes/log4j.xml file. For information on configuring log4j, please see: http://en.wikipedia.org/wiki/Log4j#Configuration

Of note, the following settings will change the verbosity of the log files and how long each daily log is kept.

[xml,N] <param name="Threshold" value="INFO"/> <param name="MaxBackupIndex" value="15"/>

Threshold can have values from most verbose to least of: TRACE, DEBUG, INFO, WARN, ERROR and FATAL.

The MaxBackupIndex is the number of daily logs to keep for each log file type, which is 15 by default.

CRS Log Configuration

The custom CRS log for the enPortal proxy is not handled by log4j. The log files are not rotated, but there are some controls you can implement to manage the size and content of the CRS log.

• Example: Observe the following lines in [INSTALL_HOME]/server/webapps/enportal/WEB-INF/config/logger-crs.properties:
  • handlers.crsFile.class=com.edgetech.util.logger.FileHandler
  • handlers.crsFile.fileName=crs.log
• You could add the following line to logger-crs-custom.properties to limit the size of this particular log file to about 1 MB:
  • handlers.crsFile.maxSize=1024000
• Masking controls are also provided for controlling the verbosity of what is written to a number of the log files. The mask uses bits to turn on/off various information, and can be the sum of any of (0,1,2,4,8).
