FastX log files
System Logs
- /var/log/fastx — stdout and stderr of the FastX Web service
- If FastX is version 2.3 or later, and the Linux system uses systemd init system (default on RedHat/Centos 7.14, Debian 8, Ubuntu 15, or SUSE 12 or later), then FastX will not log in /var/log/fastx, but the log can be viewed with the command journalctl –unit=fastx.service.
Session Logs
FastX stores all logs related to sessions in the user’s $HOME/.fastx_server/hostname.example.com/FX-sessionId/ directory
The files include:
- app_error — stderr output of the command when the session was started
- app_output — stdout output of the command when the session was started
- server_log — output of the Xorg server
- xorg.log — detailed output of Xorg
- monitor_output — logs of communication with the FastX web server
