prometheus+grafana替代Zabbix监控springboot

​

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！
