NPCD Messages

Hi,

I'm running XI 5.11.1 on Red Hat 9.

I'm seeing the following appear in /var/log/messages

npcd[1254218]: Use of uninitialized value $NAGIOS{"MULTI_PARENT"} in printf at /usr/local/nagios/libexec/process_perfdata.pl line 466, <PDFILE> line 3.

Performance graphs seem to be generating OK.

Has anyone ever seen messages like these?

Hey @andyb4u

I haven't seen these message before however I haven't installed an xi instance on rhel 9. Was this on a fresh install, and if not do you notice these messages frequently?

[richiecoy]

Did you ever get this fixed?

[andyb4u]

No i haven't found a resolution for this.

It was actually a migration of XI from a RedHat 7 server to a RedHat 9 server. XI has since been upgraded to 5.11.2 but still seeing the messages appear.

Ah it makes more sense that you are seeing these issues now that you did a migration from rhel7 to rhel9. Unfortunately migrating XI servers can be very touchy so weird issues can appear after the migration. May I ask did you follow the documentation for migrating the server found here Migrating XI to new servers unfortunate ... of issues ?

Ran in this particular issue myself after an upgrade to a newer OS since CentOS 7 is no more. I know this is a late reply, but it might help someone who runs into the same issue.
What I did to fix it;
tail /var/log/messages -n 100
Log gets flooded by messages below:
Use of uninitialized value $NAGIOS{"MULTI_PARENT"} in printf at /usr/local/nagios/libexec/process_perfdata.pl line 466, <PDFILE> line 17.
Use of uninitialized value $NAGIOS{"MULTI_PARENT"} in substitution (s///) at /usr/local/nagios/libexec/process_perfdata.pl line 465, <PDFILE> line 41.

vi /usr/local/nagios/libexec/process_perfdata.pl

Replace following line:
$NAGIOS{MULTI_PARENT} = $data[0]{multi_parent};

With:
$NAGIOS{MULTI_PARENT} = $data[0]{multi_parent} || "";

Now again do: tail /var/log/messages -n 100
Log gets flooded with messages below:
Use of uninitialized value $string in substitution (s///) at /usr/local/nagios/libexec/process_perfdata.pl line 700, <PDFILE> line 11.

vi /usr/local/nagios/libexec/process_perfdata.pl
Replace following lines:
sub cleanup {
my $string = shift;
$string =~ s/[ :\/\\]/_/g;
return $string;
}

With:
sub cleanup {
my $string = shift;
if ($string) {
$string =~ s/[ :\/\\]/_/g;
}
return $string;
}

Final check on the logs to see if the errors are gon:
tail /var/log/messages -n 100

And finally, check after 15 minutes or so to see if your performance graphs are still updating.

Keep in mind that you might have to redo this once Nagios gets updated!
