Accessing PCP/Squeezelite Client log?

I've got a playerOutputUnderrun error for some ALAC files in my LMS log, but I can't figure out how to access the squeezelite log on the PCP client tio continue the RCA.

Couldn't find the log in the device UI so figured itv was via SSH.

Got as far as logging in via SSH, but no further. I'm not majorly familiar with Linux command line, so guidance would be appreciated.

Thanks
