Heartbeat Discovery

When enabled, the Heartbeat Discovery method refreshes SMS client computer discovery data in the SMS site database. When disabled, client discovery data is refreshed only when another discovery method is invoked or run on a schedule. The Heartbeat Discovery method is useful for keeping discovery data up to date without running other discovery methods.

Heartbeat Discovery DDRs are generated on clients during their refresh cycle. The client refresh cycle runs when you start an SMS client, when you update the SMS client configuration by using the Systems Management icon in Control Panel, or every 25 hours. When the client refresh cycle runs, it generates a DDR if the time since the generation of the last DDR is greater than the frequency at which Heartbeat Discovery is set.
