SpringBoot 2.x + Prometheus + Grafana 实现应用监控

1. 简介

  提到监控系统，zabbix具有绝对的地位，它提供分布式系统监视以及网络监视功能的企业级的开源解决方案，能监视各种网络参数，保证服务器系统的安全运营，并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。但是针对于容器监控却有点力不从心，因此出现了Prometheus。Prometheus是一个开源的服务监控系统时间序列数据库，通过Http请求拉取被监控的服务暴露的端点公开的度量列表和值，然后存放到时序数据库中。最好再通过 Grafana的Dashboard进行图表展示分析和告警。
  本文基于SpringBoot 2.3.4.RELEASE版本开发的应用，通过Prometheus采集数据，最后通过Grafana可视化监控。

  Docker部署SpringBoot项目
  Docker 配置国内镜像源加速

4. SpirngBoot应用

  • 创建项目

  • 创建测试Controller，提供1000个线程方法
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 测试Controller
 * 
 * @author CL
 *
 */
@RestController
@RequestMapping("/test")
public class TestController {

	private static final Logger logger = LoggerFactory.getLogger(TestController.class);

	/**
	 * 创建线程
	 * 
	 * @return
	 */
	@RequestMapping("")
	public String test() {
		for (int i = 0; i < 1000; i++) {
			new Thread(() -> {
				logger.info(Thread.currentThread().getName());
			}).start();
		}
		return "success";
	}

}
  • 创建启动类
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * 启动类
 * 
 * @author CL
 *
 */
@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}

}
  • 在resources目录下创建application.yml配置文件

5. Prometheus采集应用指标

  • 创建配置文件
# 创建文件夹/prometheus
cd /usr/local/

mkdir prometheus

# 创建配置文件
vi prometheus.yml

# 插入以下内容
scrape_configs: 
  - job_name: monitor-demo
    scrape_interval: 5s
    scrape_timeout: 5s
    metrics_path: /actuator/prometheus
    scheme: http
    basic_auth:
      username: admin
      password: 123456
    static_configs:
      - targets:
        - 192.168.0.100:8888

# 退出并保存
:wq

docker pull prom/prometheus
docker images

docker run --name=prometheus --privileged=true -p 9090:9090 -m 500M -v /usr/local/prometheus/prometheus.yml:/prometheus.yml -v /usr/local/prometheus/data:/data -d prom/prometheus --config.file=/prometheus.yml

docker ps

6. Grafana可视化监控

docker pull grafana/grafana
docker images

docker run --name=grafana -p 3000:3000 -d grafana/grafana
  • 访问Grafana
      浏览器访问：http://192.168.0.100:3000，输入用户名密码：admin/admin。
  • 配置DataSource

  • 配置监控面板Dashboard
      页面中可选择DataSource，可更改图标样式（Visualization），可配置多个指标（Metrics），指标值需要根据Prometheus中采集的指标填写，也可更改图标的时间区间。
      浏览器访问：http://192.168.0.100:9090/graph查询采集的指标名称：

      配置可视化面板：

  • 配置结果展示
  • 补充
      Grafana还支持自动告警，具体请自行查阅。
