  2. A scenario of using Event Monitor Listener1 Listener2 EventMonitor ControlCenter register( "host1:2024" ) register( "host2:2381" ) event( "S12 failed" ) notify( "S12 failed" ) notify( "S12 failed" ) unregister( "host1:2024" ) event("S12 restarted") notify( "S12 restarted" )

  3. Internal interface of Event Monitor void event( const char* event_description );

  4. notify event External interface of Event Monitor register, unregister "R|host:port" - registration request "U|host:port" - unregistration request "N|event_desc" - event notification

  5. Support library of Event Monitor void register_listener( const char* addr ); void unregister_listener( const char* addr );
