The probe recognizes when a BMC Patrol agent loses its connection to the probe and it attempts to reconnect to that agent. The Probe for BMC Patrol V9 caches in memory the EventID of the last event read from each agent. If the connection between the agent and the probe is lost, the probe is able to request all new events from the last known EventID.
Additionally, the probe writes the last EventID from each agent to a recovery file. The probe can read this recovery file on startup and request any events that may have occurred since the probe last ran. For information about the recovery properties, see Properties and command line options.
