Log shipper offline buffering: how to keep logs safe when the destination goes down
Offline buffering is a log shipper’s ability to store events in memory or on disk while the destination is unreachable, then forward them automatically once the connection recovers. Without it, every SIEM outage, network partition, or agent restart becomes a permanent gap in your security telemetry.
Every SIEM eventually goes down. So does the WAN link to your central collector, and eventually the host running the agent itself. None of these events should cost you log data, but whether they do depends on how your log shipper buffers when it can’t deliver data to the destination.
