* Dependency the toolkit, such as using maven or gradle
|
|
```xml
|
|
<dependency>
|
|
<groupId>org.apache.skywalking</groupId>
|
|
<artifactId>apm-toolkit-micrometer-registry</artifactId>
|
|
<version>${skywalking.version}</version>
|
|
</dependency>
|
|
```
|
|
|
|
* Using `org.apache.skywalking.apm.meter.micrometer.SkywalkingMeterRegistry` as the registry, it could forward the MicroMeter collected metrics to OAP server.
|
|
```java
|
|
import org.apache.skywalking.apm.meter.micrometer.SkywalkingMeterRegistry;
|
|
|
|
SkywalkingMeterRegistry registry = new SkywalkingMeterRegistry();
|
|
|
|
// If you has some counter want to rate by agent side
|
|
SkywalkingConfig config = new SkywalkingConfig(Arrays.asList("test_rate_counter"));
|
|
new SkywalkingMeterRegistry(config);
|
|
|
|
// Also you could using composite registry to combine multiple meter registry, such as collect to Skywalking and prometheus
|
|
CompositeMeterRegistry compositeRegistry = new CompositeMeterRegistry();
|
|
compositeRegistry.add(new PrometheusMeterRegistry(PrometheusConfig.DEFAULT));
|
|
compositeRegistry.add(new SkywalkingMeterRegistry());
|
|
```
|
|
|
|
* Using snake case as the naming convention. Such as `test.meter` will be send to `test_meter`.
|
|
|
|
* Using `Millisecond` as the time unit.
|
|
|
|
* Adapt micrometer data convention.
