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:
| Log File | Description |
|---|---|
| appBoard.log.[date] | All messages related to client-server communications Information about data queries made to the server Java runtime error messages Other errors and warnings |
| error.log.[date] | Subset of appBoard.log, containing only Error messages |
| ldap.log.[date] | Messages related to LDAP |
| localhost_access_log.[date].txt | Detail of all individual user HTTP requests made to the system. Note: AppBoard/enPortal does not log access to specific individual Widgets or Boards, but could enable debugging of all data queries so that those could be audited. |
| session.log.[date] | Detail of all User sessions in the system, including: - Timestamp |
| system.log.[date] | All errors, warnings, and informational messages related to the enPortal server. including: - Expired license errors |
| 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 [INSTALL_HOME]/server/webapps/enportal/WEB-INF/config/, including settings such as the following:
[ini,N]
- 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=${logger.logs.path}/localhost_access_log
logwatch.access.numberToKeep=7
logwatch.access.compress=true
logwatch.access.skiplast=true
- Log cleanup settings
logwatch.appBoard.prefix=${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.
enPortal 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).
