nice plugin but it has some bugs

The plugin is returning the right values but if you test it will never return warning or critical because the last if is not correct.
To fix it replace it with:
if ( $cpu_status eq “critical” or $switchfabricutil_status eq “critical” or $sysbufferutil_status eq “critical” ) {
print “SNMP_ENVIRONMENT CRITICAL : $OUTPUT
“;
exit $STATE_CRITICAL;
}
elsif ( $cpu_status eq “warning” or $switchfabricutil_status eq “warning” or $sysbufferutil_status eq “warning” ) {
print “SNMP_ENVIRONMENT WARNING : $OUTPUT
“;
exit $STATE_WARNING;
}
else {
print “SNMP_ENVIRONMENT OK : $OUTPUT
“;
exit $STATE_OK;
}

Anyway thanks a lot for the plugin.
