nrpe and NetBackup Plugin

[Tao Yaoning]

the check_nb_queque works its output looks like "OK - Queue is of normal
size [0]"
the check_nb_jukebox works too, output looks like "OK - all drives are up."

but the check_nb_errs still doesn't work error message looks like
"CHECK_NRPE: Error receiving data from daemon."
The permission has no problem. I can run this command as nagios on local
machine, and get output like "ERRORS: (59 total) 1.) bptm has error-level
general error: cannot count up drives, device manager daemon (ltid) may not
be running. 2.) bptm has error-level general error: cannot count up drives,
device manager daemon (ltid) may not be running. 3.) bptm has error-level
general error: cannot count up drives, device manager daemon (ltid) may not
be running. 4.) bptm has error-level general error: cannot count up drives,
device manager daemon (ltid) may not be running. 5.) bptm has error-level
general error: cannot count up drives, device manager daemon (ltid) may not
be running. 6.) bptm has error-level general error: cannot count up drives,
device manager daemon (ltid) may not be running.
.............................."

the script for output is
if (defined(@errors)) {
if ($critcount) { $status = CRITICAL; }
elsif ($warncount) { $status = WARNING; }
else { $status = UNKNOWN; }
# print "NETBACKUP ERRORS: (" . ( $critcount + $warncount ) . " total) ";
print "ERRORS: (" . ( $critcount + $warncount ) . " total) ";
my $counta = 0;
foreach my $errorline (@errors) {
$counta++;
print "$counta.) $errorline ";
}
print "\n";
} else {
# print "No Netbackup errors found.\n";
print "OK: No Netbackup errors found.\n";
}

I get debug from strace
