Open sourcing kubenetmon: how we monitor data transfer in ClickHouse Cloud

We've created a tool called kubenetmon to monitor data transfer in ClickHouse Cloud, which provides visibility into network behavior and helps organizations forecast cloud costs. The solution collects connection data from conntrack, attributes connections to endpoints using Kubernetes informers, and stores the records in a SummingMergeTree table in ClickHouse, enabling efficient querying and analysis of network traffic patterns. By open sourcing kubenetmon, we aim to provide a valuable resource for teams managing complex cloud infrastructure.
