# DEV Notes:
#
# failregex is based on the default pattern given in Guacamole documentation :
# https://guacamole.apache.org/doc/gug/configuring-guacamole.html#webapp-logging
#
# The following logback.xml Guacamole configuration file can then be used accordingly :
# <configuration>
#   <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
#     <file>/var/log/guacamole.log</file>
#     <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
#       <fileNamePattern>/var/log/guacamole.%d.log.gz</fileNamePattern>
#       <maxHistory>32</maxHistory>
#     </rollingPolicy>
#     <encoder>
#       <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
#     </encoder>
#   </appender>
#   <root level="info">
#     <appender-ref ref="FILE" />
#   </root>
# </configuration>
