Inter-component communication

We'll call "message" to each data unit that each component (managers and agents) exchanges between them.

Kinds of messages:

Event message: An event is a message that indicates that something happened in the agent. It means a change in the agent state. Logs and results of commands are examples of event messages. They may become alerts.
State message: These messages report the state of the agent. They are related to system inventory and results of scans, among others. They won't become alerts.
Control message
: They are part of the protocol of several components between the manager and the agent. Control messages request an action. Notification payloads, WPK files transmission/execution requests, Active Response messages, remote configuration requests, and database synchronization verification messages belong to this kind of messages.
