New install of Nextcloud - error message with A non-numeric value encountered at DefaultOs.php#52

[pvuchetich]

Asking how/where best to communicate a minor FreeBSD-specific (or at least a non-Linux-specific) fix (or perhaps it is fixed in most recent FreeNAS / Nextcloud):

System: FreeNAS-11.2-U7 (most recent version is 11.3-U1 at this time), I installed the plugin for nextcloud, which appears to be 17.0.1 (most recent stable is 18.0.2)

http://[nextcloud local IP]/index.php/settings/admin/logging
shows error message:
A non-numeric value encountered at /usr/local/www/nextcloud/apps-pkg/serverinfo/lib/OperatingSystems/DefaultOs.php#52

A quick internet search shows a github issue that is exactly the same issue:

A non-numeric value encountered at DefaultOs.php#52 · Issue #172 · nextcloud/serverinfo

When browsing the /serverinfo section of my admin panel, I get on the error log: A non-numeric value encountered at /usr/local/www/nextcloud/apps/serverinfo/lib/OperatingSystems/DefaultOs.php#52 Th...

The cause is simply that it is using a Linux-specific command

Code:

 public function getMemory() {
                $memory = shell_exec('cat /proc/meminfo  | grep -i \'MemTotal\' | cut -f 2 -d ":" | awk \'{$1=$1}1\'');
                $memory = explode(' ', $memory);
                $memory = round($memory[0] / 1024);
                if ($memory < 1024) {
                        $memory = $memory . ' MB';
                } else {
                        $memory = round($memory / 1024, 1) . ' GB';
                }
                return $memory;

In the FreeNAS Nextcloud Jail, the Linux /proc directory is empty

Code:

FreeNAS#sudo iocage console nextcloud
root@nextcloud:~ # cat /proc/meminfo
cat: /proc/meminfo: No such file or directory

root@nextcloud:/proc # ls -al
total 9
dr-xr-xr-x   2 root  wheel   2 Jun 21  2018 .
drwxr-xr-x  18 root  wheel  22 Mar 24 06:52 ..

The best solution would be to modify the upstream file to use the OS-specific command to get memory and other statistics.
So, the question for this plugin is whether that would be to put it as a github request or a modification to the plugin via FreeNAS?

Thanks,
