Every SBC Manager ISO installation writes its complete output to a single log file:

/var/log/sbc-manager-install.log

Watching the log live during installation

The unattended installer prints a banner and a heartbeat line to the console every 60 seconds, but the detailed output goes to the log file. To watch it in real time while the install is still running:

1. On the server console, press Alt+F2 to switch to the second virtual console (on a VM, send Alt+F2 through your hypervisor's console viewer).
2. Press Enter to activate the shell.
3. Run:

tail -f /target/var/log/sbc-manager-install.log

Note the /target prefix — during installation the new system is mounted at /target, so the log lives at /target/var/log/... until the first reboot. Press Alt+F1 to switch back to the installer screen.

Viewing the log after installation

After the appliance reboots, log in as root (on the console or over SSH) and view the same file at its normal path:

less /var/log/sbc-manager-install.log

Useful variations:

# Show only errors and warnings
grep -iE 'error|fail|warn' /var/log/sbc-manager-install.log
Show the last 100 lines (where a failed install usually stops)
tail -n 100 /var/log/sbc-manager-install.log

Confirming the install completed

A fully provisioned appliance writes a marker file:

ls /var/lib/sbc-manager/provisioned

If that file is missing, the stack install did not complete — review the end of /var/log/sbc-manager-install.log for the failing step, and include the log file when contacting support@siplive.net.
