The probe can disconnect from the target system if the connection between them becomes unavailable.
You can use the HeartbeatInterval property to specify whether the probe periodically checks that the connection to the target system is available and how often it performs that check. The probe shuts down if it detects that the connection to the target system is unavailable.
When the HeartbeatInterval property has a value of 0 the probe does not check the availability of the connection. Any other positive value defines the number of seconds between each check of the connection's availability.
To check the connection to the target system, the probe sends a ping command (using the standard function EmsSession_I_ping) and waits for a response from the target system.
The probe also disconnects from the target system if it receives an endSession request from the EMS. This may occur if the target system restarts or is shut down.
