DUNE::Daemon Class Reference

Detailed Description

DUNE::Daemon, on dune startup, is responsible for retrieving IMC addresses and user-defined profiles, and loading saved configuration parameters.

After this steps DUNE::Daemon starts DUNE::Tasks::Manager which will then start all other dune's tasks. Finally, DUNE::Daemon is reponsible for dispatching the system's heartbeat, cpu usage, query entity state and query power channel state, until DUNE is closed.
