summary
Project updates since last year: the code splits into Horizon (rapid releases) and Meridian, with Horizons 21–23 adding concrete features. Minions run remote collectors for redundancy and edge collection; telemetryd ingests NetFlow/jFlow/sFlow, enriches records, and writes to Elasticsearch/Cassandra via Kafka/ActiveMQ — one customer stores ~20,000 datapoints/sec and production sees ~100,000 flows/sec (target ~200–250k). Sentinel offloads telemetry runtime to scale across sites, and DBSCAN-based Sextant clusters alarms into “situations,” replacing Cisco Prime for at least one user. MQTT and Grafana/Helm integrations exist.
