OPEN TELEMETRY EVOLUTION Greek word Open + Tele + Metry Open Source + Remote + Measurement --------------------------------- Merged from two projects Open Tracing + Open Census OPEN TELEMETRY INTRODUCTION

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
