It Is More Than Just Correlation - A Debug Journey - Simon Pasquier & Vanessa Martini, Red Hat
Workloads running on Kubernetes can break in many different and subtle ways, which are often hard to diagnose. Ideally, we would have many observability signals at our disposal to understand what happens and how to fix it: alerts, metrics, logs, and traces. Besides these traditional observability signals, the Kubernetes API also provides useful information such as resources’ metadata, status, and events. With so many different data sources available, the main challenge is making sense of this firehose of data and correlating the different signals in a meaningful way. The talk will focus on korrel8, a new open source tool, which aims - through the correlation of observability signals - at reducing the cognitive load of engineers when attempting to debug issues.
