--mode interface-health produces "Use of uninitialized value in string eq" with --servertype linuxlocal #228

Hello lausser,

when I run the following command, I get an "use of uninitialized value" error:

/usr/lib64/nagios/plugins/check_nwc_health -H localhost --mode interface-status --servertype linuxlocal

Use of uninitialized value in string eq at ./check_nwc_health line 59150.

The error does not appear when I use the following additional arguments:

--regexp true --name "bond0|lo|em"

This is the affected code:

if ($tmpif->{ifOperStatus} eq 'unknown') {
    $tmpif->{ifOperStatus} = $tmpif->{ifCarrier} ? 'up' : 'down';
}

Thanks and servus

Can you run it with "-vv" and withous "--name..." please. Then post the output.

Here is the output:
