Spring Boot: statistics of APIs using http.server.requests

Question

I want to statistics API requests in my Spring Boot 2 application,

Total number of requests processed

Total number of requests resulted in an OK response

Total number of requests resulted in a 4xx response

Total number of requests resulted in a 5xx response

Average response time of all requests

Max response time of all requests

I want to use Spring Boot Actuator and Micrometer, specifically, actuator/metrics/http.server.requests

But I have issues working with tag, Do I need any special configuration for the tag working? Thanks in advance.

UPDATE:

Finally, Both http://localhost:8080/travel/actuator/metrics/http.server.requests?tag=uri:/test/1 and http://localhost:8080/travel/actuator/metrics/http.server.requests?tag=status:200 work, by removing the second context path, /travel.

Answer 1

While making a request to /http.server.requests which only requires the endpoint of API to get the metrics for the particular endpoint.

As the application has a context path defined as the i.e /travel which is only required for making a request to endpoints.

Will work fine

http://localhost:8080/travel/actuator/metrics/http.server.requests?tag=uri:/test/1

do not work because of the context path in tag=uri

http://localhost:8080/travel/actuator/metrics/http.server.requests?tag=uri:/travel/test/1
