Passive check listed as Disabled

I have been using Nagios for a while, but only with active checks.
Today I started testing passive checks. I have installed nsca and everything is working as expected.
However, the passive check is listed as Disabled in the Nagios webui. Is there a way to fix this?
- Webui
Version: Nagios Core 4.0.8.
OS: Linux.

You will need to add the following to the service check in question to enable passive checks.

I already have "passive_checks_enabled 1".
Here's the service definition:
Code: Select all
define service {
service_description Passive Check
check_command check_null
passive_checks_enabled 1
active_checks_enabled 0
host_name radon
use lgq-service-nosms
}
lgq-service-nosms:
Code: Select all
define service {
name lgq-service-nosms
register 0
max_check_attempts 3
check_interval 5
retry_interval 1
first_notification_delay 0
notification_interval 240
notification_options w,u,c,r
active_checks_enabled 1
passive_checks_enabled 1
notifications_enabled 1
check_freshness 0
check_period 24x7
notification_period 24x7
contact_groups adminsNOSMS
}

Let's see some excerpts from your nagios configuration:
Code: Select all
grep passive /usr/local/nagios/etc/nagios.cfg

No settings was commented out so I removed the comments from the output.
Code: Select all
# grep passive /usr/local/nagios/etc/nagios.cfg|grep -v "^#"
log_passive_checks=0
accept_passive_service_checks=1
accept_passive_host_checks=1
translate_passive_host_checks=0
passive_host_checks_are_soft=0

Can you go to that service in the GUI and enable passive checks?
Does it stay enabled when you do that?

The service already had passive checks enabled in the GUI:
- Service in GUI
I tried "Stop accepting passive checks for this service" and then "Start accepting passive checks for this service" again.
Didn't help.
I also tried "Enable active checks for this service" and then "Disable active checks of this service".
No change. The service is still marked as Disabled.

The Tactical screen is showing that the Active Check is disabled, not the passive check, so it seems to be correct if the active check is disabled for that service.

But this service will never have an active check. Just a passive one.
As long as the definition is
Code: Select all
..
passive_checks_enabled 1
active_checks_enabled 0
..
the service should not be listed as if the active check is disabled.
I thought active check disabled meant "there is an active check defined for this service, but at the moment it's disabled for some reason"?

The Tactical Overview is suppose to show if an active check is disabled, it is there to get a quick overview of whats enabled, disabled, up, down, etc...
Here is the description of Active Checks.
