Nagios Plugin for Tape Libraries...

So I'm stuck at the office and this plugin we wrote has been such a
lifesaver, I figured I'd give it out to the community...

Here is our GroundWork GDMA external command, you may have to use your own
mechanism for running this on a vanilla Nagios environment...

Check_networker_edl[1]_Enable="ON"
Check_networker_edl[1]_Service="check_networker_edl"
Check_networker_edl[1]_Command="check_networker_edl.pl full 10 5"

Basically run the command...

"check_networker_edl.pl full 10 5"

10TB left is a WARNING
5TB left is a CRITICAL

Here is the check command we use (note that the EDL name is hard coded into
the program, please feel free to improve it):
cat check_networker_edl.pl
#!/usr/bin/perl
use strict;
use warnings;
my $pool = $ARGV[0];
my $warnvalue = $ARGV[1];
my $critvalue = $ARGV[2];

my < at > info = qx(/bin/echo "show current capacity\nprint type: NSR jukebox
; name: *EDL*" | /usr/sbin/nsradmin -i -);
my $lista = join ('', < at > info);
my < at > pools = split(',',$lista);
#print "$pools[0] \n";
if ($#ARGV < 2) {
die "Usage: check_networker_edl.pl pool warnvalue
critvalue \n";
}#end if

if ($pool eq "full")
{
my < at > full_s = split(' ',$pools[0]);
my $full_v = $full_s[2];
for ($full_s[3])
{
if ($full_s[3] eq "GB") { $full_v = ($full_v/1024);
$full_s[3]='TB';}
elsif ($full_s[3] eq "KB") { $full_v = (($full_v/1024)/1024);
$full_s[3]='TB'; }
else { $full_v = $full_s[2] }

}
for ($full_v)
{
if ($full_v < $critvalue) { print "CRITICAL - Storage space on
the *EDL* lower than the critical value of $critvalue $full_s[3] Free:
$full_v $full_s[3] \n"; exit 2; }
if ($full_v < $warnvalue) { print "WARNING - Storage space on
the *EDL* lower than the warning value of $warnvalue $full_s[3] Free:
$full_v $full_s[3] \n"; exit 1; }
else { print "OK - Storage space is OK for the* EDL* Free:
$full_v $full_s[3]\n"; exit 0; }
}

}

Here is the output from the running plugin:
# ./check_networker_edl.pl full 10 5
WARNING - Storage space on the EDL lower than the warning value of 10 TB
Free: 6.013671875 TB
