Monitoring Golden Signals with Istio on GKE
When you run a system in production, you need to be aware of what is happening. Metrics, logs and traces can help with that. There is a very popular book about Site Reliability Engineering (SRE) that proposes to focus on the four golden signals: Latency, Traffic, Errors, Saturation. In this lab we will explore how we can monitor these signals out of the box with Istio on Google Kubernetes Engine.
