How Netflix Accurately Attributes eBPF Flow Logs
- Netflix uses eBPF and TCP tracepoints to capture TCP flow logs at scale for network insights.
- FlowExporter generates flow log records including IP addresses, ports, and timestamps, with around 5 million records per second.
- Attributing IP addresses accurately to workload identities is crucial for making flow logs useful.
- Initially, misattribution issues arose due to delays in IP address change events reaching FlowCollector.
- FlowCollector's new attribution method involves correctly attributing local and remote IP addresses.
- For container workloads, IPManAgent assists in assigning IP addresses to workload IDs.
- Accurate attribution of IP addresses is achieved by maintaining time ranges of IP address ownership.
- A broadcasting mechanism using Kafka helps in sharing IP address time ranges among FlowCollector nodes.
- Cross-regional IP address attribution is facilitated by forwarding flows to nodes in the corresponding region.
- Verification of the new attribution method was done by analyzing flow logs of a large service with known dependencies.
