package autodiscovery

This package is a core piece of the agent. It is responsible for collecting check configurations from different sources (see package config providers) and then schedule or unschedule integration configurations with the help of the schedulers.

It is also responsible for listening to container-related events and resolve template configurations that would match them.

AutoConfig

As a central component, AutoConfig owns and orchestrates several key modules:

• it owns a reference to a MetaScheduler that dispatches integrations configs for scheduling or unscheduling to all registered schedulers. There are 3 scheduler implementations: checks scheduler and logs scheduler in the agent, and cluster checks dispatcher in the cluster agent.
• it stores a list of ConfigProviders and poll them according to their poll policy via configPollers
• it owns ServiceListener used to listen to lifecycle events of containers and other kind of services like network devices, kubernetes Endpoints and Service objects
• it uses the ConfigResolver that resolves a configuration template to an actual configuration based on a service matching the template. A template matches a service if they have in common at least one AD identifier element
• it uses a store component to safely store and retrieve all data and mappings needed for the autodiscovery lifecycle
