EventMesh Metrics (OpenTelemetry and Prometheus)

EventMesh Metrics (OpenTelemetry and Prometheus)

Introduction

EventMesh(incubating) is a dynamic cloud-native eventing infrastructure.

An overview of OpenTelemetry

OpenTelemetry is a collection of tools, APIs, and SDKs. You can use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) for analysis in order to understand your software’s performance and behavior.
