com.corundumstudio.socketio.handler.HeartbeatHandler
com.vaadin.server.communication.HeartbeatHandler
Handles heartbeat requests. Heartbeat requests are periodically sent by the client-side to inform the server that the UI sending the heartbeat is still alive (the browser window is open, the connection is up) even when there are no UIDL requests for a prolonged period of time. UIs that do not receive either heartbeat or UIDL requests are eventually removed from the session and garbage collected. @author Vaadin Ltd @since 7.1
org.apache.ambari.server.agent.HeartBeatHandler
This class handles the heartbeats coming from the agent, passes on the information to other modules and processes the queue to send heartbeat response.
org.apache.sling.discovery.impl.common.heartbeat.HeartbeatHandler
The heartbeat handler is responsible and capable of issuing both local and remote heartbeats and registers a periodic job with the scheduler for doing so.
Local heartbeats are stored in the repository. Remote heartbeats are POSTs to remote TopologyConnectorServlets.
