Blancco Management Console activity is logged in detail. Sometimes troubleshooting an issue might require inspecting the log files.
When generating the log files, two folders are created, config and logs. In addition, an sdt_report.txt is created from the Blancco Management Console Diagnostics Core which includes some system information and list of collected files from BMC.
config -folder
build.properties - BMC information used when building the service
configuration.properties - All active configuration settings
log4j2.xml - Logging settings for BMC log files
main.properties - General, database, BI and report transfer settings
server.xml - Tomcat's main configuration file, includes the server port and HTTP Connector settings
wrapper.conf - Wrapper properties
logs -folder
audit.log - Logs all user activity
bmc_access_log - HTTP requests handled by the web server
host-manager.log - Logs of any related web applications (not used in BMC)
install.log - Logs from the initial install of BMC
localhost.log - Logs of the host
main.log - General activity of the service
manager.log - Logs of any related web applications (not used in BMC)
trace.log - Logs HTTP communication with erasure clients and Asset Management System (AMS), needs to be enabled by editing the logging level of log4j2.xml to trace
wrapper.log - Wrapper logs
Note! All access log files (bmc_access_log.*) that are older (modification time) than 28 days, are automatically deleted. The deletion happens after the first HTTP request after 00:00:00, when it also creates the new access log file for that day.

Configuring BMC logging levels
Blancco Management Console uses standard Apache Log4j2 as the logging framework. In addition, Apache Tomcat implements the access logging.
Following directories are used for storing log files:
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:
trace - log all HTTP communication messages with erasure clients and Asset Management System (AMS)
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.
