About Really Small Message Broker

Communication between the Network Manager core components is managed by Really Small Message Broker. To ensure the correct operation of Network Manager, Really Small Message Broker must be running at all times.

Various Network Manager core components pass information to other components on the same server, and to any Network Manager core components on different servers.

This communication is managed by Really Small Message Broker.

Really Small Message Broker is installed and started automatically by the Network Manager installation process.

If you stop Really Small Message Broker while core Network Manager processes such as the Discovery engine, ncp_disco, are running, then the core processes will restart Really Small Message Broker automatically.

Note: Running multiple domains in parallel can overload the message broker on some systems. If you want to run multiple domains under load in parallel then it is good practice to run a separate message broker for each domain.
