Nagios Service Dependencies

[Dei Bertine]

Hi Jim,

Thanks for clarifying to me et al, I will definitely give this a shot. 

I'm sure this will benefit the others who thought of building this config in their Nagios, especially for a newbie like I... :-) 

Cheers, 
DB

I would put service dependencies in a file called something like
'servicedependencies.cfg'.

in nagios.cfg, you need a pointer to this new file, for example:

cfg_file=/usr/local/nagios/etc/objects/servicedependencies.cfg

The nagios.cfg file should only contain the main configuration file
options which you'll find documented in
http://nagios.sourceforge.net/docs/3_0/configmain.html

But ... I'm not convinced you should need service dependencies for
'ping' from one host to another.  Nagios handles this sort of thing
automatically if you configure the host parent relationships.  See:

http://nagios.sourceforge.net/docs/3_0/networkreachability.html

hth,

Jim
