Subject: Using service dependencies 


Hi, 
 
I'm trying to use service dependencies as part of my nagios config. 
 
Basically, I want to do 2 checks, the primary check connects to a database.
The secondary check is for RAM usage. 
However, if the primary check fails I don't want nagios to try and attempt
the secondary check as there is no point if 
a system is down. I still want to see Nagios alert via the web front-end but
not be notified via email when the primary check 
is in a Unknown or Critical state. 
 
(The plugins on their own all work fine thru nagios as do they via the
command-line. )
 
I've defined below what I understand to be the way to configure dependencies
but i'm not convinced its right even though 
it works fine. Could someone take a look and just sanity check this for me
and let me know if i'm doing the right/wrong thing ? 
 
thx

PS All of the lines below currently sit in my services.cfg until I know it
works and then i'll split the dependency to a different cfg file. 
Its easier to make changes that way!

define service{
        use                     generic-service            ; Name of host
