After decades of every vendor/project/application building their own implementation for these, we're finally going to have a commonly available implementation and standard from the OpenTelemetry project:

From the site: "OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools."
