service dependency on host?

Hi,
I have nagios up and working but I want to tweak it some so I'm not
getting buried under sms messages.
My setup works like so.
I have a file called Loc-Servers.cfg
In this file it has the host definitions that look like this, but just
a ton of them....
# serv01
define host{
use linux-server
host_name serv01.example.com
alias serv01
address 192.168.1.101
}
# serv01
define host{
use linux-server
host_name serv02.example.com
alias serv02
address 192.168.1.102
}
And then after the hosts I have the services setup generally like this:
define service{
use generic-service
host_name serv01.example.com,
serv02.example.com
service_description Ping
check_command check_ping!100.0,20%!500.0,60%
}
My real question comes down to dependencies. As much as I love getting
400 messages if something 'upstream' goes down like a switch, I
generally want to try to get alerts only for hosts down and alerts for
the first point of failure.
So assuming one of my networks look like this:
Router --> Switch -> serv01, serv02, serv03
Lets say the switch goes down. Which makes the servers all
unreachable, which fails out all other servers. I don't want to have
any notifications really for anything below the switch.
I've seen the docs about having services dependent on services, and
hosts dependent on hosts. But how about services, dependent on hosts.
Do I just use hosts instead of services in the config?
Thanks for you time and for your help,
Charlie
