what is the good args to enable jaeger opentracing?

```
          - --tracing.serviceName=traefik-service
          - --tracing=true
          - --tracing.jaeger.samplingServerURL=http://my-jaeger-agent.jaeger:5778/sampling
          - --tracing.jaeger.localAgentHostPort=my-jaeger-agent.jaeger::6831

```

On my jaeger instance I only see trace for jaeger not for traefik  
Need I add something into IngressRoute or service to see the trace of each call inside Jaeger ?  
Is it better to use agent or collector ?

@ldez Are you sure that traefik with jaeger works fine? I think I've try all possible configuration without any success.(by collector or agent)

@Idez see somethink really strange. If I use the clusterIp it works. but not with the dns name.  
see:

```
          "--tracing.serviceName=tracing",
          "--tracing=true",
          "--tracing.jaeger=true",
          "--tracing.jaeger.samplingType=const",
          "--tracing.jaeger.samplingParam=1.0",
          "--tracing.jaeger.samplingServerURL=http://my-jaeger-agent.jaeger.svc.cluster.local:5778/sampling",
          "--tracing.jaeger.collector.endpoint=http://my-jaeger-collector.jaeger.svc.cluster.local:14268/api/traces?format=jaeger.thrift"

```

doesnt works  
if I replace "--tracing.jaeger.collector.endpoint=http://my-jaeger-collector.jaeger.svc.cluster.local:14268/api/traces?format=jaeger.thrift" by "--tracing.jaeger.collector.endpoint=http://10.100.200.55:14268/api/traces?format=jaeger.thrift" it works

Inside log file I see:  
time="2020-03-19T15:08:00Z" level=error msg="Tracing jaeger error: error reporting Jaeger span "kube-system-middleware-https@kubernetescrd": Post [http://my-jaeger-collector.jaeger.svc.cluster.local:14268/api/traces?format=jaeger.thrift:](http://my-jaeger-collector.jaeger.svc.cluster.local:14268/api/traces?format=jaeger.thrift:) dial tcp: lookup my-jaeger-collector.jaeger.svc.cluster.local on 169.254.0.2:53: no such host" tracingProviderName=jaeger

I have a smoothly traefik + jaeger integration using service name resolution. Please have a look at below:

```auto
            - --tracing.jaeger=true
            - --tracing.serviceName=traefik-service
            - --tracing.jaeger.samplingParam=1.0
            - --tracing.jaeger.samplingType=const
            - --tracing.jaeger.localAgentHostPort=jaeger-operator-jaeger-agent.monitoring:6831
            - --tracing.jaeger.samplingServerURL=http://jaeger-operator-jaeger-agent.monitoring:5778/sampling

```
