Transactions .netCore

**Elasticsearch version: Cloud (7.8)

APM Agent language and version: Elastic.Apm (1.6) with the nuget NetCoreAll

Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):

I'm using the service map functionality but It doesn't show the relations between the services and I don't understand the reason. I have 2 applications like Api - Service and this is the result:

But I have one trace with the information:

I have been searching the answer and I think that the reason is that i have one transaction in excess.

The green register looks like a internal listener of the agent or something like this, I don't Know if is correct:

Thanks for the help.

Hi @Kirtash,

We released a patch 2 days ago that addresses this issue - its version number is 1.6.1. Could you try that one?

Now the is correct but not appears the representation in the service map yet :frowning:

@Kirtash what do you mean by this?

but not appears the representation in the service map yet

You still see the 2 services, but they are still not connected? Make sure you select the right time frame.

If it still does not work, could you show me the full document where is GET localhost ? (it's the 2. one on your screenshot)

First of all, thanks for the answer GregKalapos.

Correct, not appears the connection. Do you want the stacktrace? If I copy all the document I reach to the max lenght of the message :frowning: This is the all the document without the stacktrace.

thanks for pasting the document - that already shows the problem.

The agent is version 1.6.0, but the fix is in 1.6.1. - Make sure you update to the latest.

@GregKalapos now is working and appears the connection between the services :slight_smile: I don't know why the agent didn't update but now is perfect.

Thanks for the help!
