APIs have existed nearly as long as websites themselves. But because APIs are primarily consumed by programs instead of people, they tend to be less visible than applications or sites directly accessed by users. The result: APIs often receive far less attention from a site reliability engineering (SRE) and monitoring perspective than other parts of application environments.

From the moment Elastic announced plans to abandon a pure open source license for its Elasticsearch engine and Kibana dashboards in early 2021, there’s been a massive effort underway to create clear alternatives for the global community of active users. Logz.io has been an outspoken advocate and contributor to this work – fully embracing it as part of our product roadmap to best serve the needs of our customers, and preserve our long-term commitment to open source observability.

Kubernetes monitoring is a critical process for keeping your Kubernetes clusters running in fine health. In this tutorial, we will learn everything about Kubernetes monitoring. We will be using two open-source tools: OpenTelemetry and SigNoz, to monitor a Kubernetes cluster, so you can follow along with the tutorial easily.
