[Fwd: Re: Service Dependencies - How do you doyours?]

[Matthew Joyce]

I prefixed the serviced which depended on an SNMP service  "SNMP -",
then I cobbled a python script to search for those services.
It outputs a single service_dependency_HOSTNAME_SNMP file which I put in
a service_dependencies folder.
 
Each time I add a server or service I run this script and pass the host
name to it.
It works well, I'll probably do the same for NRPE.
 
The only thing that stops me sharing the script is that it's a real
kludge and once it worked I stopped working on it.

	Hari,
	
	I have this exact problem (raised it a few weeks ago.)
	I've got it on my to-do list to create a shell script (probably
PHP) 
	that will create a service_dependencies.cfg file for you with
each host 
	and it's NRPE services.
	
	I'll try and get round to it this weekend and post on Nagios
Exchange.  
	I'll probably even post it as a page on my webserver so you
won't have 
	to have PHP locally.
	
	HTH
	
	Andy.
