Overview
In the post, we are going to trace http requests with the help of a spring boot actuator.
Tracing http requests with the help of spring boot actuator
Firstly, add spring-boot-starter-actuator dependency to the pom.xml file:
1
2
3
4
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
Secondly, enable HTTP tracing by adding the following Configuration bean to the project:
1
2
3
4
5
6
7
8
9
@Configuration
public class HttpTraceActuatorConfiguration {
@Bean
public HttpTraceRepository httpTraceRepository() {
return new InMemoryHttpTraceRepository();
}
}
We have to do it because Actuator HTTP Trace and Auditing features are not enabled by default anymore in Spring-Boot-2.2.0.
Thirdly, Add the following lines to the application.properties:
1
2
management.endpoints.web.exposure.include=httptrace
management.endpoints.enabled-by-default=true
or in yml format:
1
2
3
4
5
6
management:
endpoints:
web:
exposure:
include: "httptrace"
enabled-by-default: true
You could find all available endpoints here.
Lastly, you could check out out the last 100 http requests by the following link: http://localhost:8080/actuator/httptrace
Replace hostname and port if needed.
Conclusion
We have described how to trace http requests with the help of a spring boot actuator.
