Metrics

Metrics can be two types:

• Standard
• Custom

Standard metrics

Description Standard metrics see spring-boot metrics

How to add?

Example

Step 1. Add pom.xml new dependency.

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

Step 2. Add permission to SecurityConfig.java

.antMatchers("/actuator/metrics/**").permitAll()

Step 3. Add new environment to application.yml

    management:
        endpoint:
            metrics:
                enabled: true
    endpoints:
        enabled-by-default: true
        web:
            exposure:
                include: 'metrics'

Custom metrics

You can see the number of requests in different sections.

Live Sample Statistics of all requests to UI

Live Sample Statistics of all requests to screen clients and user

Example request:

../actuator/metrics/platform-requests?tag=<section name>:<section value>

http://demo.cxbox.org/actuator/metrics/platform-requests?tag=screen:clientAll requests to screen clients

You can filter by several sections at once.

http://demo.cxbox.org/actuator/metrics/platform-requests?tag=screen:client&tag=user:JOHN%20SNOW All requests to user and screen clients

Step 4. Add description custom metrics:screen,bc,crudmaAction,error,user.

Custom metrics start name: "platform-requests"
