Heartbeating

When the connection is lost between the fault adapter and the device, heartbeating allows the probe to determine whether the device is still alive. If the heartbeating feature is enabled and the target system fails, the probe tries to ping the fault adapter module until it is active again. The probe then reestablishes a connection and starts to acquire alert data again. If the system fails to respond to the heartbeats, the probe disconnects from the device.

If the probe fails to receive any data for the number of seconds specified by the HeartbeatInterval property, it pings the fault adapter. If the probe does not receive the ping within the time specified by the HearbeatTimeout property, the probe disconnects and switches to reconnection mode. The HeatbeatRetry property allows you to specify how many times the probe sends heartbeats to the device before disconnecting.
