The java app configuration, at startup should tell you if you have connected to the APM Server... are you verifying this?

If you have no data... there is an error logged somewhere or a misconfiguration. How is your java app configured with apm agent ?

Yeah, from java app logs, it says to be connected

```

APP is configured manually with apm agent

```auto
JAVA_OPTS="${JAVA_OPTS} -javaagent:/app/apm-agent.jar"
JAVA_OPTS="${JAVA_OPTS} -Delastic.apm.server_url=${APM_SERVER_URI}"
JAVA_OPTS="${JAVA_OPTS} -Delastic.apm.verify_server_cert=false"
JAVA_OPTS="${JAVA_OPTS} -Delastic.apm.service_name=apm-rules-data"
JAVA_OPTS="${JAVA_OPTS} -Delastic.apm.application_packages=com.test"

```

At least it should show server start up logs, right?

The AMM agent is registered correctly with the Service Name so that is good. it seems more that there are no transactions or spans to send ? This is more to do with your application, you can turn on the debug for more details on if your java application is sending anything.

HealthCheck is basic transaction which is logging at INFO level and can be seen in app log.  
Same transaction and traces is present in APM.

```

**Is there any other configuration need to be done on APM to poll the logs?** eg: Fleet agent?

I think, logging integration is required to embedd logs into the APM UI. But how 🤔 🤔

If something is being registered, then the APM agent seems fine, maybe this is your application issue ?

What i understood from logs is, we need to app logs in ES to correlate with APM

So i used fluent bit to send logs to ES

Now, how can we correlate fluent bit logs to APM logs?

Normally this will be via the timestamp, but for proper instrumentation, there should be a correlation id present in both the APM & Logs.

Please see i have transaction id in metadata of APM transaction and In Kibana we have logs for this transaction id, still it does n't show in APM logs
