Business Process Monitoring with Anomaly Detection in Practice

DevOps teams within Swisscom are responsible for ensuring that any issues that could affect users are quickly addressed. This quest is challenging due to the high volume of available metrics, events, and traces (~300GB daily).
We will show how we designed and deployed an anomaly detection system based on Prophet models, PySpark, and MLflow, which analyses performance, throughput, and error metrics of important business processes. These analytics are displayed in an end-to-end monitoring tool which provides a holistic view of many distributed systems and gives actionable insights to the teams.
