How to integrate the "metrics" and "trace" data

The "trace" comes from "uber-jaeger-client -> jaeger-agent -> openTelemetry".
"trace" information:

The "metric" is crawling the service's port 9102 through the "prometheus_simple" of "openTelemetry". The service exposes "metrics" data via "prometheus/client_golang/prometheus".

import 	(
       "github.com/prometheus/client_golang/prometheus/promhttp"
       "net/http"
)
http.Handle("/metrics", promhttp.Handler())

The "lb" is our company abbreviation.
