Changing the logging format

The server stores its log by using Apache Log4j. You can edit the Log4j settings to change the format of the log and the information that is added to the log.

About this task

The Log4j logging settings are stored in the file app_data/conf/server/log4j.properties, where app_data is the application data folder. You can edit this file directly on the server or open it by clicking Settings > Logging.

For example, to log all REST calls that are made to the server, uncomment the following lines of code at the bottom of the file:

log4j.appender.audit=org.apache.log4j.RollingFileAppender
log4j.appender.audit.File=../var/log/user_audit.log
log4j.appender.audit.MaxFileSize=10MB
log4j.appender.audit.MaxBackupIndex=5
log4j.appender.audit.layout=org.apache.log4j.PatternLayout
log4j.appender.audit.layout.ConversionPattern=%d{ISO8601} - %m%n

log4j.additivity.com.urbancode.ds.web.filter.LoggingFilter=false
log4j.logger.com.urbancode.ds.web.filter.LoggingFilter=DEBUG, audit

Now, all REST calls are stored in the file server/var/log/user_audit.log, as in the following example:

2015-08-05 11:20:23,882 - User admin from host 127.0.0.1
accessing: GET @ /rest/deploy/environment
2015-08-05 11:20:24,009 - User admin from host 127.0.0.1
accessing: POST @ /rest/deploy/environment/compliancies
