# Spring sleuth setup
Spring Sleuth provides Spring Boot auto-configuration for distributed tracing. Skywalking integrates it's micrometer part,
and it can send metrics to the Skywalking [Meter System](./../../concepts-and-designs/meter.md).
## Set up agent
1. Add the Micrometer and Skywalking meter registry dependency into project `pom.xml` file. Also you could found more detail at [Toolkit micrometer](./../service-agent/java-agent/Application-toolkit-micrometer.md).
```xml
org.springframework.boot
spring-boot-starter-actuator
org.apache.skywalking
apm-toolkit-micrometer-registry
${skywalking.version}
```
2. Create the Skywalking meter resgitry into spring bean management.
```java
@Bean
SkywalkingMeterRegistry skywalkingMeterRegistry() {
// Add rate configs If you need, otherwise using none args construct
SkywalkingConfig config = new SkywalkingConfig(Arrays.asList(""));
return new SkywalkingMeterRegistry(config);
}
```
## Set up backend receiver
1. Make sure enable meter receiver in the `applicaiton.yml`.
```yaml
receiver-meter:
selector: ${SW_RECEIVER_METER:default}
default:
```
2. Configure the meter config file, It already has the [spring sleuth meter config](../../../../oap-server/server-bootstrap/src/main/resources/meter-analyzer-config/spring-sleuth.yaml).
If you also has some customized meter at the agent side, please read [meter document](backend-meter.md#meters-configure) to configure meter.
3. Enable Spring sleuth config in the `applicaiton.yml`.
```yaml
agent-analyzer:
selector: ${SW_AGENT_ANALYZER:default}
default:
meterAnalyzerActiveFiles: ${SW_METER_ANALYZER_ACTIVE_FILES:spring-sleuth}
```
## Add UI dashboard
1. Open the dashboard view, click `edit` button to edit the templates.
