Jaeger Agent metrics not returned #738
Description
As per the documentation the Jaeger Agent should expose some metrics properly formatted for Prometheus on :5778/metrics
The Agent is started using:
docker run \
--rm \
-p5775:5775/udp \
-p6831:6831/udp \
-p6832:6832/udp \
-p5778:5778/tcp \
jaegertracing/jaeger-agent:1.2 \
/go/bin/agent-linux --collector.host-port=my-collector:some-port
And I tried to retrieve the metrics using:
curl -v localhost:5778/metrics
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 5778 (#0)
> GET /metrics HTTP/1.1
> Host: localhost:5778
> User-Agent: curl/7.54.0
> Accept: */*
