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
环境准备
- 简单webapi
spring boot 集成了prometheus,详细代码就不贴了，只提供简单的pom 配置

主要集成了zulu、oracle、openjdk 以及granfana，prometheus
version: "3"services: zulu: build: context: ./zulu dockerfile: Dockerfile ports: - "8080:8080" oracle: build: context: ./oracle dockerfile: Dockerfile ports: - "8081:8080" openjdk: build: context: ./openjdk dockerfile: Dockerfile ports: - "8082:8080" grafana: image: grafana/grafana ports: - "3000:3000" prometheus: image: prom/prometheus volumes: - "./prometheus.yml:/etc/prometheus/prometheus.yml" ports: - "9090:9090" - 各jvm 运行dockerfile
zulu Dockerfile

FROM frolvlad/alpine-java:jdk8-slimFROM 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
- grafana dashborad 配置
可以参考项目中的grafana/dashboard.json - prometheus 配置
使用静态配置prometheus.yml 文件
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/shrm -rf jdk/*.logfor file in jdk/*; do nohup bash $file > $file.log &done启动&&测试
- 启动
docker-compose up -dcd load-test && sh start.sh- 配置granfana
需要配置premetheus server 地址，以及初始化中账户的处理
加载dashborad json 文件，在grafana/dashboard.json 
- prometheus 效果
- granfana dashborad 的参数效果
- 简单说明
因为测试上的很随意实际上是有问题的，但是zulu 优化上的openjdk 总体还是很不错的,连接有一篇别人的测试，可以参考，但是也是不完备的
