# Configuration
To adapt the Elastic APM Java agent to your needs, you can configure it using one of the methods below, listed in descending order of precedence:
1. <definitions>
   <definition term="Central configuration">
   Configure the Agent in the Kibana APM app. [![dynamic config](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/images/dynamic-config.svg) ](#configuration-dynamic)
   </definition>
   </definitions>
2. <definitions>
   <definition term="Properties file">
   The `elasticapm.properties` file is located in the same folder as the agent jar, or provided through the [`config_file`](/elastic/docs-builder/docs/2322/reference/apm/agents/java/config-core#config-config-file) option. ![dynamic config](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/images/dynamic-config.svg)
   </definition>
   </definitions>
3. <definitions>
   <definition term="Java system properties">
   All configuration keys are prefixed with `elastic.apm.` ![dynamic config](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/images/dynamic-config.svg)
   </definition>
   </definitions>
4. <definitions>
   <definition term="Environment variables">
   All configuration keys are in uppercase and prefixed with `ELASTIC_APM_`.
   </definition>
   </definitions>
5. <definitions>
   <definition term="Runtime attach parameters">
   1. `--config` parameter. See [Automatic setup with `apm-agent-attach-cli.jar`](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/setup-attach-cli).
   </definition>
   </definitions>

1. Arguments of `ElasticApmAttacher.attach(...)`. See [Programmatic API setup to self-attach](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/setup-attach-api).
2. `elasticapm.properties` in classpath root with `ElasticApmAttacher.attach()`. See [Programmatic API setup to self-attach](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/setup-attach-api).

1. <definitions>
   <definition term="Default values">
   Defined for each configuration.
   </definition>
   </definitions>


## Dynamic configuration ![dynamic config](https://www.elastic.co/elastic/docs-builder/docs/2322/reference/apm/agents/java/images/dynamic-config.svg)

Configuration options marked with Dynamic true can be changed at runtime when set from supported sources:
- [Central configuration](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2322/solutions/observability/apm/apm-agents/central-configuration)
- `elasticapm.properties` file
- Java system properties, but only when set from within the application

<note>
  There are two distinct ways to use `elasticapm.properties`: as an external configuration file, and as a classpath resource. Only the external file can be used for dynamic configuration.
</note>


## Minimal configuration

In order to get started with Elastic APM, the most important configuration options are [`service_name`](/elastic/docs-builder/docs/2322/reference/apm/agents/java/config-core#config-service-name), [`server_url`](/elastic/docs-builder/docs/2322/reference/apm/agents/java/config-reporter#config-server-url) and [`application_packages`](/elastic/docs-builder/docs/2322/reference/apm/agents/java/config-stacktrace#config-application-packages). Note that even these settings are optional. Click on their name to see how the default values are determined.
An example configuration looks like this:
```bash
-Delastic.apm.service_name=my-cool-service
-Delastic.apm.application_packages=org.example,org.another.example
-Delastic.apm.server_url=http://127.0.0.1:8200
```

```properties
service_name=my-cool-service
application_packages=org.example,org.another.example
server_url=http://127.0.0.1:8200
```

```bash
ELASTIC_APM_SERVICE_NAME=my-cool-service
ELASTIC_APM_APPLICATION_PACKAGES=org.example,org.another.example
ELASTIC_APM_SERVER_URL=http://127.0.0.1:8200
```
