Hi and thanks for trying out the agent!
Please add logging.level.co.elastic.apm=DEBUG in application.properties and look out for logs of co.elastic.apm, wich may be truncated to c.e.a..
Could you also post your docker (compose) configuration?
from apm-agent-java.

This line is interesting, although probably not related to the problem that no data is sent:

Can you see any logs related to elastic apm after you perform a request against your application?

Seems like the agent ist working but the connection to the apm server is not.
It also seems there is at least one line missing after
Sending payload to APM server failed
There should be the exception class and message.
If your container supports it, can you try to curl the apm server from it?
How do you start the apm server? Do you expose the port 8200?

Hi @felixbarny, So I get this Exception from the log
Caused by: java.net.ConnectException: Connection refused (Connection refused)
And here's what I get when I curl from the container with apm-agent running in it.
/ # curl "http://127.0.0.1:8200"
curl: (7) Failed to connect to 127.0.0.1 port 8200: Connection refused

apm server is running on the same host as the apm agent and of course port 8200 is exposed.
These two containers share a same network.

Can you curl the apm server from your local machine?
It should look like:
$ curl localhost:8200

Can you look into the docker logs of the apm server?

I just learned that it was company firewall that blocked the connection to apm-server from apm-agent. so when a payload is being sent via http protocal, instead of hitting apm-server container within the same custom docker network directly, the agent tried to resolve the domain from the internet and that's where I got connection refused. I now see the apm data in kibana just fine. Thank you very much for identifying the source of the problem. @felixbarny you are a hero!

That's great to hear!
Did everything else work as expected? Anything in particular you like or dislike about the agent?

Once the network issue is gone, everything worked as expected. I really like the automatic span detection. I didn't have write anything in the application yet the agent picks up necessary information and delivers them nicely. Really helpful in "application performance monitoring"
I tried zipkin before but apm-server/apm-agent are way more user friendly. Just would like some improvements on the documentation though. For example, I had some hard time figuring out starting the agent because I followed the code in the getting started,
java -jar my-spring-boot-application.jar -javaagent:/path/to/elastic-apm-agent-<version>.jar
and later I found that you need to specify -javaagent:/path/to/elastic-apm-agent-<version>.jar part before -jar <my-app>.jar
So in my case, the agent runs correctly after switching the position of the -javaagent part.
java -javaagent:/path/to/elastic-apm-agent-<version>.jar -jar my-spring-boot-application.jar
so simple things like this can really improve the experience. Other than this, I am very happy with the product. real good job!
