Transitioning from Prometheus to OpenTelemetry - A Journey of a Cluster's Metrics Evolution

Part 1: A Brief Introduction

With this blog post, we kick off a series on evolving our Kubernetes metrics stack. Our journey to replace Prometheus with an OpenTelemetry solution begins with an introduction OpenTelemetry and why we see it as a valid alternative to our current implementation. After explaining the main parts of the OpenTelemetry project and briefly reviewing its history, we discuss the pros and cons. After reading this, you will be able to follow along our hands-on and deep-tech posts on how we optimize our metrics stack.

Part 2: Scraping The First Metrics

Having explained the technical implementation of the monitoring stack in our latest blog post, this article focuses on replacing Prometheus with OpenTelemetry Collector to decouple scraping from the storage and query mechanisms. The OpenTelemetry Collector uses various building blocks to construct the telemetry pipeline and requires enabling of the target allocator. Guiding you through this process we provide various practical tips, including processor ordering and horizontal autoscaling."
