Open Telemetry

Slide deck related to the Singapore Java User Group (JUG) presentation on OpenTelemetry. The demo covered setting up Open Telemetry from locally using Docker, Docker Compose and Single node Kubernetes cluster in Docker Desktop. In the last part we cover the managed Kubernetes cluster using Azure Kubernetes Service (AKS)

6. OPEN TELEMETRY EVOLUTION Greek word Open + Tele + Metry Open Source + Remote + Measurement --------------------------------- Merged from two projects Open Tracing + Open Census OPEN TELEMETRY INTRODUCTION
7. OPEN TELEMETRY INTRODUCTION • OpenTelemetry is an Observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs. • Crucially, OpenTelemetry is vendor and tool-agnostic, meaning that it can be used with a broad variety of Observability backends, including open source tools like Jaeger and Prometheus, as well as commercial offerings. OpenTelemetry is a Cloud Native Computing Foundation (CNCF) project. OFFICIAL DEFINITION
