Spring sleuth setup

Spring Sleuth provides Spring Boot auto-configuration for distributed tracing. Skywalking integrates its micrometer so that it can send metrics to the Skywalking Meter System.

Set up agent

  1. Add micrometer and Skywalking meter registry dependency into the project’s pom.xml file. You can find more details at Toolkit micrometer.
  1. Create Skywalking meter registry in spring bean management.
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 to enable meter receiver in application.yml.
  selector: ${SW_RECEIVER_METER:default}
  1. Configure the meter config file. It already has the spring sleuth meter config. If you have a customized meter at the agent side, please configure the meter using the steps set out in the meter document.

  2. Enable Spring sleuth config in application.yml.

  selector: ${SW_AGENT_ANALYZER:default}
    meterAnalyzerActiveFiles: ${SW_METER_ANALYZER_ACTIVE_FILES:spring-sleuth}
