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
- 参考项目
https://github.com/rongfengliang/zulu-openjdk-openjdk-oracle-jdk - 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

- docker-compose 环境
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 azul/zulu-openjdk-alpine:8u222
LABEL AUTHOR="dalongrong"
LABEL EMAIL="1141591465@qq.com"
WORKDIR /
COPY jmx_prometheus_javaagent-0.12.0.jar /jmx_prometheus_javaagent-0.12.0.jar
COPY webapi-0.0.1-SNAPSHOT.jar /webapi-0.0.1-SNAPSHOT.jar
COPY docker-entrypiont.sh /docker-entrypiont.sh
RUN chmod +x /docker-entrypiont.sh
EXPOSE 8080 9999 30384
ENTRYPOINT [ "/docker-entrypiont.sh" ]
docker-entrypiont.sh:
#!/bin/sh
java -jar /webapi-0.0.1-SNAPSHOT.jar
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
- 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/sh
rm -rf jdk/*.log
for file in jdk/*; do
nohup bash $file > $file.log &
done
启动&&测试
- 启动
docker-compose up -d
cd 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。
