The FSC creates logs for all system processes. By default, all log files on the FSC are written to a temporary partition in volatile memory that is reset every time the device is rebooted. You can also configure the FSC to stream the logs to the Control Center syslog server. For troubleshooting purposes, you can enable persistent logging directly to the SD card of the FSC. Enabling persistent logging is not recommended because it decreases the lifetime of the SD card.
- /var/phion/logs/c3c.log – Log file for the communication between FSCs and the Control Center.
- /var/phion/logs/cudavpn.log – FSC VPN service log file.
- /var/phion/logs/scactl.log – Web UI log file
- /var/phion/logs/shorewall/shorewall.log – Logs connections denied by the FSC Firewall service.
- /var/phion/logs/shorewall/shorewall-init.log – Log file containing firewall activation logs.
Syslog streaming to the Control Center allows you to process the log files using the Control Center syslog service.The FSC streams over UDP port 5140.
