java - 获取端点的指标

Question

我有一个 API 端点，现在我想跟踪每当向我的端点发出请求时，有多少个返回 200，有多少个返回 400 或其他 HTTP 状态代码，请告知我如何实现在 Spring Boot 项目中也是如此，我使用的是 Spring Boot Actuator 2。

假设我的端点是:

https://localhost:9090/users

所以我想要的是:

{  
    "404": 1,
    "200": 6,
    "409": 1
}

Answer 1

您可以使用 /actuator/metrics/ 获取所有执行/调用的端点及其计数、异常、结果、状态、总时间等。这种情况计数、状态很有用

为此，您必须在 pom.xml 中添加依赖项或类似的等级

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

获取执行/调用的所有 endPoint 的详细信息(查看所有 endPoint 的结果)

localhost:8889/actuator/metrics/http.server.requests

<小时/>

要获取特定终点的详细信息(请参阅特定结果 端点)

localhost:8889/actuator/metrics/http.server.requests?tag=uri:<endPoint>
localhost:8889/actuator/metrics/http.server.requests?tag=uri:/users

<小时/>

获取带有状态代码的特定端点的计数(参见结果 带有状态代码的特定端点)

localhost:8889/actuator/metrics/http.server.requests?tag=uri:/users&tag=status:200
