We currently have the device send log information to the controller using the log API, and this can be useful when debugging issues in EVE.
However, in some cases it is useful to also be able to inspect the current state. That state could be the state maintained by the EVE microservices (e.g., the AppInstanceStatus maintained by zedmanager), or it could be external state such as the iptables or ps process output.
This proposal specifies how a well-defined set of such information can be retrieved by the controller.
