I'm trying to determine how I might be able to keep a group of states (modules) from having direct knowledge about each other, while still allowing them to put and get configuration information on a local-to-the-minion level.

For example, my nginx related states and config should have no knowledge about logstash and where it might put a config file. Instead I want the logstash to make it known (how is the question) that it has a log file available for consumption.

Say I have a logstash process running on a machine and it's configuration looks something like the below. Right now it's going to read in just one log file, but in just a bit I want it to read in any log file that another service, managed via a role/state, might add.

/etc/logstash/agent.conf
