Logging view (device) not showing logs

Dear,

The logging view in the device page seems to be broken. It is not generating the warning

print_warning('<h4>No syslog entries found!</h4>
This device does not have any syslog entries.
Check that the syslog daemon and Observium configuration options are set correctly, that this device is configured to send syslog to Observium and that there are no firewalls blocking the messages.

See <a href="'.OBSERVIUM_URL.'/wiki/Category:Documentation" target="_blank">documentation</a> and <a href="'.OBSERVIUM_URL.'/wiki/Configuration_Options#Syslog_Settings" target="_blank">configuration options</a> for more information.');
}

as stated in pages/device/logs/syslog.inc.php

instead it does seem to trigger the function print_syslogs($vars); but it does not return any results. I don't see any reference to the $vars variable in the certain page either so I suspect it is being initialized in another page on which this page is included.

This bug is applicable to all log views in the log tab on the device pages.

Kind regards,
