Something isn’t quite working as expected? Here are some guidelines how to find out what’s going wrong.

Don’t worry if you can’t figure out what the problem is. Open a topic in the APM discuss forum and we will help you out. If you do so, please attach your debug logs so that we can analyze the problem.


There are several logging related configuration options. The most important one is logging.log_leveledit. Set the log level to DEBUG or even TRACE to get more information about the behavior of the agent.


Sometimes reading the logs is just not enough to debug a problem. As the agent is OpenSource and released on Maven Central, debugging the agent code is really easy.

In order for your IDE to download the sources, first declare a dependency to the agent.


The agent is added via the -javaagent flag. So you have to make sure that you declare the dependency in a way that the agent is not on the classpath twice. For example, when you are developing a web application, make sure that the agent is not packaged in your war in WEB-INF/lib. In the debug window of your IDE, make sure that elastic-apm-agent does not appear in the -classpath.




Even when setting the scope to provided, IntelliJ sometimes adds the agent on the classpath anyway. One workaround is to set the scope to test.


compileOnly "co.elastic.apm:elastic-apm-agent:$elasticApmVersion"

Common problemsedit

There is no data in the Kibana APM UIedit

The most common source of this problem are connection issues between the agent and the APM server.

If the APM server does not receive data from the agent, check if the agent is able to establish a connection to the server. In the agent logs, look out for logs containing Elastic APM server is available and Elastic APM server is not available.

If you see the message Elastic APM server is not available, the agent has problems connecting to the APM server. Check the setting of server_urledit and make sure the agent is able to connect to the server. Try to execute curl -v <apm-server-url>/healthcheck from the machine the agent is running on. The server should respond with a 200 status code.

If the APM server does not respond successfully, have a look at the APM server logs to verify that the server is actually running. Also make sure to configure your firewalls so that the host the agent runs on can open HTTP connections to the APM server.
