I declared two passive service as bellow:
define service{
use remote-service
host_name AAA
service_description AAA_managed3_srm_state
check_command nsca_passive
notifications_enabled 1
active_checks_enabled 0
passive_checks_enabled 1
event_handler_enabled 1
event_handler state_event_handler
}

define service{
use remote-service
host_name BBB
service_description BBB_managed8_srm_state
check_command nsca_passive
notifications_enabled 1
active_checks_enabled 0
passive_checks_enabled 1
event_handler_enabled 1
event_handler state_event_handler
}

PS: nsca_passive is a command I declared as none:
define command{
command_name nsca_passive
command_line none
}

Then I declared a dependency service dependent above two services as bellow:
define servicedependency {
dependent_host_name localhost
dependent_service_description srm_state
host_name AAA
service_description AAA_managed3_srm_state
execution_failure_criteria o,w,c,u
notification_failure_criteria o,w,c,u
}

define servicedependency {
dependent_host_name localhost
dependent_service_description srm_state
host_name BBB
service_description BBB_managed8_srm_state
execution_failure_criteria o,w,c,u
notification_failure_criteria o,w,c,u
}

define service{
use remote-service
host_name localhost
service_description srm_state
check_command nsca_passive
#check_freshness 1
#freshness_threshold 5
active_checks_enabled 0
passive_checks_enabled 1
event_handler_enabled 1
event_handler state_event_handler
}

PS: There are programs send state for service "AAA_managed3_srm_state" and "BBB_managed8_srm_state" periodically, and I can see state changing from nagios UI and NagVis UI.

Problems are:
1. service state of "srm_state" always be "PENDING" and status information is "Service is not scheduled to be checked... ", seems no check on this service based on the two dependent services.
2. if one of the dependent service goes from OK to CRITICAL, no event occurred to service "srm_state".

In fact above two problems are what I need for this dependency servie "srm_state", but now I don't know how to it, is there some one has same need as I, help me!
