Abstract
Embodiments herein describe techniques for creating a lightweight snapshot of a network fabric without having to capture snapshots at a predefined interval. Instead, the snapshot system uses a data store to capture state changes to network objects in the network fabric. Because the data store captures these state changes (along with timestamps indicating when these changes occurred), the snapshot system can retroactively generate snapshots of the network fabric at any desired time. In one embodiment, the snapshot system includes an event detector that determines when to capture snapshots. Once an event is identified by the event detector, the snapshot system can use the historical changes in the data store to retroactively generate a first snapshot to capture the overall state of the network fabric before the event and a second snapshot to capture the overall state of the network fabric after the event.
