Todays architectures are loosely coupled, autoscaling and technology agnostic. Monitoring such deployments is a challenge and finding the rootcause for a user impacting service degradation even more.

In this talk we cover the challenges of transactional tracing and how we apply artificial intelligence to condense heaps of anomalies to one single root cause.
