UNRAID exit status 255 from monitor
Env:
Version: UNRAID 7.2.4
Problem:
/var/log/syslog: exit status 255 from user root /usr/local/emhttp/plugins/dynamix/scripts/monitor &> /dev/null exit status 255 from user root /usr/local/emhttp/plugins/dynamix/scripts/monitor &> /dev/null exit status 255 from user root /usr/local/emhttp/plugins/dynamix/scripts/monitor &> /dev/null |
Solution:
Test run stripts use phpdbg,The error occurs because $level (or $saved[$item][$attr]) is a string instead of a number, and PHP 8+ no longer allows implicit mathematical calculations on strings.
phpdbg /usr/local/emhttp/plugins/dynamix/scripts/monitor [Welcome to phpdbg, the interactive PHP debugger, v8.3.26] To get help using phpdbg type "help" and press enter [Please report bugs to <http://bugs.php.net/report.php>] [Successful compilation of /usr/local/emhttp/plugins/dynamix/scripts/monitor] prompt> run [Uncaught TypeError in /usr/local/emhttp/plugins/dynamix/scripts/monitor on line 90: Unsupported operand types: int * string] >00090: $last = ($saved[$item][$attr] ?? 0)*$level; 00091: if ($raw>0 || $fail) { 00092: if ($raw>$last) { |
Fix it by explicitly casting the values to integers or floats using (int) or (float),replace code in monitor line 90:
$last = int(saved.get(item, {}).get(attr, 0)) * int(level) |
