Hello,

Could you add mount option in vfs.fs.discovery ? It's very easy to add it and with this, you can monitor read-only disk and other errors.
I adapted the script in zabbix documentation to support it :

#!/usr/bin/perl
$first = 1;

print "{\n";
print "\t\"data\":[\n\n";

for (`cat /proc/mounts`)
{
($fsname,$fstype,$fsmode) = m/\S+ (\S+) (\S+) (\S+)/;
$fsname =~ s!/!
/!g;

print "\t,\n" if not $first;
$first = 0;

print "\t{\n";
print "\t\t\"

\":\"$fsname\",\n";
print "\t\t\"

\":\"$fstype\"\n";
print "\t\t\"

\":\"$fsmode\"\n";
print "\t}\n";
}

print "\n\t]\n";
print "}\n";
