# Debug with user space logs

Use the following logs to debug issues in user space through SSH on the device.

## Generate syslogs

To verify whether the device generates syslogs, run the following command:

cat /var/log/user.log
    Copy to clipboard

If the device doesn't generate syslogs, run the following command:

tail -f /var/log/messages
    Copy to clipboard

Sample log:

## Generate journalctl logs

To view the system journalctl logs, run the following command:

journalctl -ef
    Copy to clipboard

Sample log:
