The problem could be caused by retention.dat file.
All the passive host have this line : “active_checks_enabled=1”
Why ? Is it a bug ?

The two templates are:

check_command check-host-alive
active_checks_enabled 1
passive_checks_enabled 0
check_period 24x7
event_handler_enabled 0

check_freshness 1
freshness_threshold 1800
max_check_attempts 1

}
The two host configurations are:
define host{
use
generic-active-host
host_name 192.xxx.xxx.3
alias host_active_3
address 192.xxx.xxx.3
max_check_attempts 10

notifications_enabled 1
contact_groups Mine_CGs

}
define host{
use

host_name 192.xxx.xxx.4
alias host_passive_4
address 192.xxx.xxx.4
max_check_attempts 10
notification_interval 360
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups Mine_CGs
parents
}
The same for the host_1 and host_2 (mentioned bevore).

Hi all
I have 2 HG, both with active and passive hosts.
They use same templates and same parameters.
First HG behaviour is OK : in the panel we have active and passive hosts

Second HG behaviour is wrong : in the panel ALL the hosts are active, none
is passive

The “Status Informartion” is “OK” (due to the check_dummy service configured
on it) , but If you go inside the passive host 192.xxx.xxx.4 you see:
Active Checks:
ENABLED
Passive Checks:
ENABLED
Obsessing:
ENABLED
Notifications:
ENABLED
Event Handler:
DISABLED
Flap Detection:
DISABLED
I can’t udersand why and how to solve this
.
