There are basic messages that note where GUACAMOLE_HOME is, what extensions are being loaded, etc. If you're not seeing anything like the above, you may need to consult the documentation of your distro to determine where Tomcat will be logging things. Some log to files in a subdirectory of /var/log, some log to syslog, some log to the systemd journal, Docker images log to the Docker logs. This is not something Guacamole itself controls, but a factor in how Tomcat was set up. - Mike
