(EN) Handling 250K flows per second with OpenNMS: a case study

What does it take to go from no flow support, to handling huge volumes of heterogeneous flow data in a 100% open-source monitoring stack, in a real-world environment? Expect a brief refresher on flows, an overview of the customer environment, and discussion of the engineering challenges faced. A medium dive follows into the movement of flow data from ingest to query and display, the solution architecture as it exists today, and lessons learned and their application to the project roadmap.
