Chapter summary

In this chapter, you learned the three main types of telemetry are logs, metrics, and traces. Logs are application events and are a great tool for determining why an application or microservice isn’t working. Metrics provide historical trends and help identify changes over time. Traces let you track requests as they traverse today’s complex microservices apps. You also learned that the OpenTelemetry project offers specifications and instrumentation to standardise and simplify the way we generate and store telemetry.

You learned that Prometheus is the most popular monitoring platform used with Kubernetes and is often coupled with Grafana for dashboards and visualisations. It expects services to expose telemetry on the /metrics endpoint and operates a pull model where it “scrapes” the data at periodic intervals. It has a push gateway for getting telemetry from short-lived processes, and an alert manager for sending out alerts.
