In this session we will deep dive into metrics collection with the OpenTelemery project. Prometheus has been de-facto standard for metrics instrumentation and collection for a long time. Everybody is well familiar with the /metrics endpoint, the Prometheus pull approach and {Pod,Service}Monitors. In this session, we will show how OpenTelemetry can scrape Prometheus metrics using the OpenTelemetry collector, and target allocator with the OpenTelemetry operator on Kubernetes. The audience will not only learn how the setup works but also understand the benefits and shortcomings of each solution.
