1.下载可视化模板
通过上文可知grafana为显示页面，所以本文提供一份监控springboot的json页面供大家下载。

2.配置SpringBoot
1.修改pom
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.dalaoyang</groupId> <artifactId>springboot2_prometheus</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot2_prometheus</name> <description>springboot2_prometheus</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId> <version>1.1.3</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.修改application.yml
management: endpoints: web: exposure: include: '*' metrics: tags: application: ${spring.application.name} health: redis: enabled: false
3.设置application
在启动问价中加入以下代码。
@Bean MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) { return (registry) -> registry.config().commonTags("application", applicationName); }
SpringBoot项目到这里就配置完成了，启动项目，访问http://ip:8080/actuator/prometheus即可看到返回值，这些值就是spring boot返回在前台页面的信息。
3.Prometheus配置
在prometheus配置监控我们的SpringBoot应用，完整配置如下所示。找到配置文件替换即可。
# my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. # scrape_timeout is set to the global default (10s). # Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: # - alertmanager:9093 # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: # - "first_rules.yml" # - "second_rules.yml" # A scrape configuration containing exactly one endpoint to scrape: # Here it's Prometheus itself. scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. - job_name: 'prometheus' static_configs: - targets: ['localhost:9090'] - job_name: 'springboot_system' #监控任务名称 scrape_interval: 5s metrics_path: '/actuator/prometheus' static_configs: - targets: ['localhost:8088'] #springboot端口号
启动Prometheus ，访问 ip:9090，然后按照下图操作，即可看到已经注册到Prometheus 的监控任务。
4.Grafana配置
输入ip:3000，可以进入grafana的可视化界面。
1.配置prometheus数据源 （ip:9090）
上图填写你prometheus地址，端口切记填写9090，点击save后，如果失败会有提示 。
2.导入可视化模板
然后导入上文下载好的可视化界面模板。
选择上文配置好的数据源，prometheus选项就是上文配置的数据源。
3.验证
出现以上画面 配置完成！
