通过granfana 以及prometheus 比较zulu 、oracle、openjdk 等jvm 运行

说明，此测试不完备，只是一个简单的集成，详细的需要进行jvm 参数的调整

openjdk以及oracle 的都是类似，主要的不通就是基础镜像

FROM frolvlad/alpine-java:jdk8-slim

FROM openjdk:8u222-jdk

几个说明，因为spring boot 已经包含了jmx 的暴露，所以对于jmx 的处理就没有多加复杂的处理，项目中包含了一个jmx-exporter
如果需要可以添加使用

scrape_configs:

  - job_name: zulu

    metrics_path: /actuator/prometheus

    scrape_interval: 10s

    scrape_timeout: 10s

    static_configs:

      - targets: ['zulu:8080']

  - job_name: openjdk

    metrics_path: /actuator/prometheus

    scrape_interval: 10s

    scrape_timeout: 10s

    static_configs:

      - targets: ['openjdk:8080']

  - job_name: oracle

    scrape_interval: 10s

    scrape_timeout: 10s

    metrics_path: /actuator/prometheus

    static_configs:

      - targets: ['oracle:8080']

测试
使用ab 进行接口测试，地址为http://service:port/actuator/env 可以参考load-test 目录，区分了openjdk、zulu、oracle
内容为：

ab -c 10 -n 100000 http://localhost:port/actuator/env

为了同时运行，使用了一个简单的shell start.sh

#!/usr/bin/sh

rm -rf jdk/*.log

for file in jdk/*; do

 nohup bash $file > $file.log &

done

docker-compose up -d

cd load-test && sh start.sh

加载dashborad json 文件，在grafana/dashboard.json
