Network Availability: The expected continued growth of our ecosystem makes it difficult to understand our network bottlenecks and potential limits we may be reaching. Flow Collector consumes two data streams, the IP address change events from Sonar via Kafka and eBPF flow log data from the Flow Exporter sidecars.

Logs and events play an essential role in this mix; they include critical information which can’t be found anywhere else, like details on transactions, processes, users and environment changes. Without user transactions and experience data, in relation to the underlying components and events, you miss critical context.

For example, when running tests, the state of the device will change from “available for testing” to “in test.” The challenge, then, is to be able to ingest and process these events in a scalable manner, i.e., scaling with the number of devices, which will be the focus of this blog post.

Crash recovery: In the event of a system crash or restart, the undo log helps restore the database to a consistent state by applying the necessary undo operations based on the recorded before-images. This ensures that in the event of a crash, the changes recorded in the redo log can be replayed to restore the database to a consistent state.
