SpringCloud uses Zipkin to achieve tracking and monitoring of distributed services
Maven coordinates of dependent class libraries:
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>
</dependencies>
The main dependencies here are 'spring cloud starter zipkin' and 'spring cloud starter slim'` Spring cloud starter zipkin 'is a client dependency of Zipkin, used to send application tracking information to the Zipkin server` Spring cloud starter sleuth 'is the client dependency of Spring Cloud Sleuth. It provides the function of generating and managing trace information in the Microservices architecture.
The following is a complete example of using Zipkin to implement distributed service tracking and monitoring:
1. Create a Spring Boot application and add the above dependencies.
2. Configure the server address for Zipkin in 'application. properties' or' application. yml ':
yaml
spring.zipkin.base-url=http://localhost:9411
3. Add the annotation '@ Enable ZipkinServer' on the startup class to enable the Zipkin server function.
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}
4. Add the annotation '@ Enable ZipkinStreamServer' on the services that need to be tracked and monitored.
@SpringBootApplication
@EnableDiscoveryClient
@EnableZipkinStreamServer
public class ServiceApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceApplication.class, args);
}
}
5. Start the Zipkin server and service application.
Now, when your service application runs, it will send tracking information to the Zipkin server and can be monitored and analyzed through Zipkin's web interface.
The complete Java code is as follows:
Zipkin Server Startup Class' ZipkinServerApplication. java ':
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}
Service application startup class' ServiceApplication. java ':
@SpringBootApplication
@EnableDiscoveryClient
@EnableZipkinStreamServer
public class ServiceApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceApplication.class, args);
}
}
Summary: Using Zipkin can facilitate the tracking and monitoring of distributed services. By adding corresponding dependencies and configurations, you can send tracking information of your application to the Zipkin server and perform real-time monitoring and analysis through Zipkin's web interface. This is very helpful for diagnosing and solving performance issues in distributed systems.
