I have become tired of adding hosts more than once, and am now looking at methods to have hosts share configs. With only 4 monitoring servers to manage, I feel the cfEngine is an unnecessarily complex route to take for this task. My current plan is to use exactly the same host and service files on all servers, but then use local root template objects to define which services are passive. There will probably also be a few variables that will need to be set locally. I want to be able to store all my configs in my subversion repository, and check out updates onto all servers whenever I need to. Now my main question is this: Is it possible to specify an include file based on an environment variable? i.e. cfg_file=/etc/nagios/$HOSTNAME$-primary.cfg (I realise that I can probably create a soft-link called "local.cfg" and point it to the file I want, but, I would prefer to get rid of all the external dependencies.) My second question: If I go this route, can anyone assist in my research and tell me which config variables will most likely need to be set per host. Thanks Peter </BODY> </HTML>
