windows下gradle下使用windows版普罗米修斯prometheus和metrics简单的制作一个监控java环境的内存状况的教程

1.引入依赖（如果是maven可以自行翻译）：

例如：    compile 'io.prometheus:simpleclient_hotspot:0.5.0'

             groupid   为  io.prometheus

             artifactid  为     simpleclient_hotspot

             version    为    0.5.0

//普罗米修斯仪表盘监控依赖
    compile 'io.prometheus:simpleclient_hotspot:0.5.0'
    compile 'io.prometheus:simpleclient:0.5.0'
    compile 'io.prometheus:simpleclient_httpserver:0.5.0'
    compile 'io.prometheus:simpleclient_dropwizard:0.5.0'
    compile 'io.prometheus:simpleclient_servlet:0.5.0'

2.给配置文件中添加：

此处是端口暴露为9000端口

import io.prometheus.client.exporter.HTTPServer;
import io.prometheus.client.hotspot.DefaultExports;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;
import java.io.IOException;

/**
 * 作者 ZYL
 * 功能描述 : 普罗米修斯监控平台
 * 日期 2019/6/15 0015 0:38  
 * 参数 null
 * 返回值 
 */
@Configuration
public class MetricsBean {


    @PostConstruct
    public void init() throws IOException {
        DefaultExports.initialize();
        HTTPServer server = new HTTPServer(9000);
    }

}

此处可以启动Java项目了，我这里使用的是idea启动的

3.下载prometheus的windows版本

https://prometheus.io/download/

4.配置prometheus的prometheus.yml文件：此处注意-job_name:   这个参数是你的监听的应用的名称，下面的 - targets ['localhost:9000']，此处为啥是9000因为我前面的config配置文件里面暴露的是9000

# 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'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9000']

5.启动windows版本的prometheus.exe

6.访问地址：本地的是：localhost:9090，

此处需要在搜索栏写：

jvm_memory_bytes_used{job="prometheus"}

其中：job="prometheus"是自定义的，配置的什么这里写什么

7.大功告成！
