Service dependencies not working as I would think?

Hey folks,
So, after an unintentional barrage of alerts, I started playing
around with service dependencies. I do an awful lot of checks using
check_by_ssh, so I'd like to set up dependencies for other services
that depend on ssh. Simple, I would think.
In my dependencies.cfg (this is Nagios 1.2):
# Servicedependency definition
define servicedependency{
host_name neutron
service_description ssh
dependent_host_name neutron
dependent_service_description postgresql
execution_failure_criteria w,u,c ; These are the criteria
; for which check execution
; will be supressed
notification_failure_criteria w,u,c ; These are the criteria
; for which notifications
; will be supressed
}
For the above host (neutron), I use check_by_ssh to execute
check_pgsql locally. So, with the above config, I would think that
if ssh goes away, the postgresql service will not be tested and will
not alert.
To test, I killed ssh on neutron, and watched what happened -
and to my dismay, Nagios alerted on both ssh and postgresql. :(
The "view config" in the web interface seems to show the dependency
set up correctly - what the heck am I missing?
Thanks!
Benny
