nagios-check_bl

Nice Plugin! Thanks!

spudding - I had the exact same problem you did with the NULL being returned. I could run the check_bl command without issue on the command line and get a "Not Blacklisted" result back, but once I tried to add it to my config as a service I got a null in the web page. In order to fix the problem I had to modify the check_bl file itself and change a path inside of the file. Here's what I changed:

use lib "/usr/lib/nagios/plugins";

I changed it to this...

use lib "/usr/local/nagios/libexec/";

all of my plugins are located in the libexec directory. Once I did that, the nagios web page returned a correct result instead of NULL. Hope this helps!

What FQDN does it test against? All my host_names are internal names or IP's. Do I need to create an additional host with my external or FQDN and assign check_bl to that host?

Re: works great!
my checkcommands.cfg looks like that:

define command {

command_name check_bl

command_line $USER1$/check_bl -H

$HOSTADDRESS$ -B

sbl.spamhaus.org,list.dsbl.org,dnsbl.njabl.org

}

and my host.cfg:

define service {

host_name proxy1

service_description BLACKLIST

is_volatile 0

check_command

check_bl!80.21.16.14,80.21.16.16

max_check_attempts 3

normal_check_interval 60

retry_check_interval 60

active_checks_enabled 1

passive_checks_enabled 1

check_period 24x7

parallelize_check 1

obsess_over_service 1

check_freshness 0

event_handler_enabled 1

flap_detection_enabled 1

failure_prediction_enabled 1

process_perf_data 1

retain_status_information 1

retain_nonstatus_information 1

contact_groups admins

notification_interval 240

notification_period 24x7

notification_options c,r

notifications_enabled 1

register 1

}

hope this helps a little bit!
