Communicator heartbeat refers to the Control Manager agent message that notifies the Control Manager server with "I am alive" information. The Communicator provides this mechanism to determine whether the managed products remain active.
The heartbeat defines when a Communicator sends information to the Control Manager server. Use the Communicator Scheduler to define the heartbeat Working and Idle hours.
The Communicator polls the Control Manager server at regular intervals for the following purposes.
ensure that the Control Manager console displays the latest information
check whether the connection between the managed product and the server remains functional
There are three heartbeat statuses:
Active — within the Working hour
Inactive — idle hour or not within the Working hour
Abnormal — disconnected
Refer to Managed Products, Communicators, and Child Servers Connection Status Icons for details.
The Communicator sends heartbeat using the User Datagram Protocol (UDP) instead of using a connection-oriented protocol, where available.
In addition to providing periodic heartbeat to the Control Manager server, the Communicator also sends real-time managed product status information to the server.
