# Debug with user-space logs

Use the following logs to debug user-space issues 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:**
> 
> 
> Apr 28 17:42:30 qcm6490 daemon.info avahi-daemon[516]: No service file found in /etc/avahi/services.
> 
> 
> Apr 28 17:42:30 qcm6490 daemon.info avahi-daemon[516]: Joining mDNS multicast group on interface lo.IPv6 with address ::1.
> 
> 
> Apr 28 17:42:30 qcm6490 daemon.info avahi-daemon[516]: New relevant interface lo.IPv6 for mDNS.
> 
> 
> Apr 28 17:42:30 qcm6490 daemon.info avahi-daemon[516]: Joining mDNS multicast group on interface lo.IPv4 with address 127.0.0.1.
> 
> 
> Apr 28 17:42:30 qcm6490 daemon.info avahi-daemon[516]: New relevant interface lo.IPv4 for mDNS.

## Generate journalctl logs

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

> 
> 
> journalctl -ef
