This article will explain in detail how to quickly build a monitoring platform for Spring Boot Admin. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Developers who have used Springboot all know actuator, which is a functional module provided by Springboot for self-examination and monitoring of the application system. With the help of Actuator developers can easily view and count some monitoring indicators of the application system. Unfortunately, there is no visual interface, so we can only view the corresponding metrics through dry json data, as shown below:

Visual monitoring indicator platform Spring Boot Admin, which uses the functions provided by spring-boot-starter-actuator to integrate the status of various micro-services, and provides a good interface to view support, and can dynamically modify the instance log level.

Spring Boot Admin is divided into server and client, which is very easy to use. The server can check the status of each microservice, and the client registers the microservice with the server.

Server side

Let's first build the server, generate a spring boot project directly using start.spring.io, and introduce the following dependencies

Configure port and service name

Server.port=8090 spring.application.name=admin-server

Start the class by adding an annotation @ EnableAdminServer

After startup, open the url and display the following

Client

For the spring boot project, you can directly add the dependencies shown in the following figure

The server addresses that are configured for registration in application.properties are as follows

Spring.application.name=admin-client spring.boot.admin.client.url= http://127.0.0.1:8090 management.endpoints.web.exposure.include=* management.endpoint.health.show-details=ALWAYS

After the startup is complete, check the server side, as shown below

View related metrics

Apply the wall to quickly see those service exceptions

Normal situation

Abnormal situation

Click apply to view the corresponding metrics

View the environment variable configuration of properties

View log level

Spring Boot Admin provides the following functions for registered applications:

Show your health.

Displays details such as JVM and memory metrics micrometer.io metrics data source metrics cache metrics

Show internal number

Follow and download log files

View JVM system and environment properties

View Spring Boot configuration properties

Publishable / env-&/ refresh-endpoint that supports Spring Cloud

Easy log-level management

Interact with JMX-beans

View thread dump

View http-traces

View audit events

View http endpoints

View scheduled tasks

View and delete active sessions (using spring-session)

View Flyway / Liquibase database migration

Download heapdump

Status change notification (via email, Slack,Hipchat, etc.)

Event log for state changes (non-persistent)
