Hi,
I would suggest writing your own plugin if it's this specific & you
know what you're looking for. What you're wanting to do would be pretty
easy in perl (but I'm not sure what output you're looking for exactly).
here's my really quick, ugly, untested implementation =):
use lib '/usr/nagios/libexec';
use utils qw ( %ERRORS );
my @files;
push @files, (glob ('/var/mqm/exits/logs/*.log'),
glob ('/var/mqm/errors/*.FDC'));
my %errors;
for my $f (@files){
unless (open FILE, $f){
print "can't open file $f!\n"; exit $ERRORS{'UNKNOWN'}
}
my $counter = 0;
while (<FILE>){
$counter++;
if (($f =~ /log$/ && /refused/) || ($f =~ /FDC$/ && /Probe ID/)){
push @{$errors{$f}},$counter
}
}
close FILE;
}
if (!%errors){
print "OK!\n"; exit $ERRORS{'OK'}
}
else{
for my $key (sort keys %errors){
print "$key: errors at lines ", join ',',@{$errors{$key}}, " ";
}
print "\n";
exit $ERRORS{'CRITICAL'}
}
