BHM (Bundled Heartbeat Monitor) is a module which is used to monitor other Processes. When a monitored Process is uncontrolled, the BHM module will take measures, such as printing warning on screen, shutting all ports, or restarting the system, to help or remind users to recover the system.

There are three activations of BHM, including “reload system”, including “reload system”,“warning”, “shutdown port”.
