The code is check if $output is defined and including it in the notify message
if it isn't:
{code}
if (!defined($output)) {
notify($ERRORS{'WARNING'}, 0, "failed to run command to determine available
space on $computer_short_name:\ncommand: $command\noutput:\n" . join("\n",
@$output));
return;
}
{code}
