Working with Agents and Config Zones ==================================================================== Working with Icinga 2 Agents can be quite tricky, as each Agent needs its own Endpoint and Zone definition, correct parent, peering host and log settings. There may always be reasons for a completely custom-made configuration. However, I'd strongly suggest to give the Director-assisted variant at least a try first. It might save you a lot of headaches. Preparation ----------- Agent settings are not available for modification directly on a host object. This requires you to create an "Icinga Agent" template. You could name it exactly like that; it's important to use meaningful names for your templates.  As long as you're not using Satellite nodes, a single Agent zone is all you need. Otherwise, you should create one Agent template per satellite zone. If you want to move an Agent to a specific zone, just assign it the correct template and you're all done. Usage ----- Well, create a host, choose an Agent template, that's it:  Once you import the "Icinga Agent" template, you'll see a new "Agent" tab. It tries to assist you with the initial Agent setup by showing a sample config:   The preview shows that the Icinga Director would deploy multiple objects for your newly created host:  Create Agent-based services --------------------------- Similar game for services that should run on your Agents. First, create a template with a meaningful name. Then, define that Services inheriting from this template should run on your Agents.  Please do not set a cluster zone, as this would rarely be necessary. Agent-based services will always be deployed to their Agent's zone by default. All you need to do now for services that should be executed on your Agents is importing that template:  Config preview shows that everything works as expected:  It's perfectly valid to assign services to host templates. Look how the generated config differs now:  While services added to a host template are implicitly rendered as assign rules, you could of course also use your `Agent-based service` template in custom apply rules:
