**OpenTelemetry** is an open source observability framework for cloud native
software. It provides a single set of APIs, libraries, agents, and collector
services to capture distributed traces and metrics from your application.

OpenTelemetry builds upon years of experience from the OpenTracing and
OpenCensus projects, combined with best-of-breed ideas and practices from the
community.
