Applying Site Reliability Engineering 'Golden Signals' to your Kubernetes Cluster

Understanding how to monitor the "Golden Signals" of Site Reliability Engineering (SRE) in your Kubernetes cluster(s) is an important skill for any engineer, especially for Day 2 Operations. Fortunately, there are some very useful, powerful, and open source tools and technologies out there for accomplishing these tasks. This training session will go over how to monitor these "Golden Signals" in a Kubernetes cluster using Prometheus and Slack.
