Explore the relationship between alerting and anomaly detection in this 29-minute conference talk by Björn Rabenstein from Grafana Labs. Delve into the history of Prometheus and the unexpected demand for anomaly detection in monitoring systems. Learn about PromQL's capabilities in supporting anomaly detection fundamentals, while understanding the contrasting philosophy of Promethean alerting focused on SLO-based, non-noisy alerts. Gain insights from real-world pager experiences and discover why integrating anomaly detection directly into alerting systems can be problematic. Examine the recommended Promethean approach to alerting, its limitations, and potential applications of anomaly detection and machine learning within this framework.
