Monitoring at Scale: Informal Overview of Quad9's Telemetry and Monitoring

John Todd, CTO of Quad9, will provide a short summary of how Quad9 monitors 260 worldwide locations serving hundreds of billions of DNS queries per day. Quad9 uses open source platforms for all their systems. Prometheus, Grafana, Clickhouse, Vector, and Kafka are all parts of the core platform that ingests millions of events per second and turns that into hundreds of thousands of metrics and summary events that are used to improve performance and create cross-sectional understanding of application, network, and hardware performance. The talk will be informal and have time for longer Q&A.
