Blancco Management Console uses standard Apache Log4j 2 as the logging framework. In addition, Apache Tomcat implements the access logging.
Following directories are used for storing log files:
- Log4j: [Installation path]\logs\
- Apache Tomcat: [Installation path]\apache-tomcat\logs\
Log4j configuration
The configuration file is located at: [Installation path]\apache-tomcat\webapps\ROOT\WEB-INF\classes\log4j2.xml.
Blancco Management Console is required to be restarted after changes of log configuration file.
The main log level can be set by XML element: <Root level="info">
Available logging levels:
- debug - logs verbose debug information, not recommended in production
- info - the default logging level of Blancco Management Console
- audit - info level logging and audit logging to the separate file (audit.log)
- warn - logs warnings and errors
- error - logs only errors
- off - logging is completely disabled
Log4j archives old log files into ZIP files. The maximum size of open log file is defined by XML element <SizeBasedTriggeringPolicy size="100MB"/>, separately for main.log and audit.log.
Archived log files are stored into date formatted path: [Installation path]/logs/archive-logs/<yyyy-mm>/<app|audit>-yyyy-mm-dd-n.log.zip
Apache Tomcat logging configuration
The access logging is implemented by standard Apache Tomcat AccessLogValve in server.xml. By default the pattern is 'common' but also 'combined' can be used.
The access logs are written into daily files named bmc_access_log.<yyyy-mm-dd>.txt.
