OpenTelemetry (OTel) is an open-source framework designed to generate, collect, and export telemetry data such as traces, metrics, and logs, enabling a comprehensive observability strategy across various applications, services, and infrastructures. This guide provides a practical walkthrough on deploying an OpenTelemetry demo application in a Kubernetes environment and using the Logz.io exporter to send telemetry data to the Logz.io platform. It explains how to utilize OTel's vendor-neutral tools to transform and standardize raw data, allowing for greater visibility and optimization of software systems. By following the steps, users can configure the OpenTelemetry Collector to export data and explore the benefits of integrating Logz.io features such as AI-powered insights, anomaly detection, and root cause analysis. The guide also highlights the importance of enhancing observability by collecting cluster-level metrics using Logz.io's Helm shipper, thus streamlining the monitoring and troubleshooting of Kubernetes-deployed applications.
