經過granfana 以及prometheus 比較zulu 、oracle、openjdk 等jvm 運行

說明，此測試不完備，只是一個簡單的集成，詳細的須要進行jvm 參數的調整

環境準備

• 參考項目
  https://github.com/rongfengliang/zulu-openjdk-openjdk-oracle-jdk
• 簡單webapi

  spring boot 集成了prometheus,詳細代碼就不貼了，只提供簡單的pom 配置

• docker-compose 環境
  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 運行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 的都是相似，主要的不通就是基礎鏡像

FROM frolvlad/alpine-java:jdk8-slim

FROM openjdk:8u222-jdk

幾個說明，由於spring boot 已經包含了jmx 的暴露，因此對於jmx 的處理就沒有多加複雜的處理，項目中包含了一個jmx-exporter
若是須要能夠添加使用

• grafana dashborad 配置
  能夠參考項目中的grafana/dashboard.json
• prometheus 配置
  使用靜態配置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']

• 測試
  使用ab 進行接口測試，地址爲http://service:port/actuator/env 能夠參考load-test 目錄，區分了openjdk、zulu、oracle
  內容爲：

 

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

爲了同時運行，使用了一個簡單的shell start.sh

#!/usr/bin/sh

rm -rf jdk/*.log

for file in jdk/*; do

 nohup bash $file > $file.log &

done

啓動&&測試

• 啓動

docker-compose up -d

cd load-test && sh start.sh

• 配置granfana

  須要配置premetheus server 地址，以及初始化中帳戶的處理

加載dashborad json 文件，在grafana/dashboard.json

 

• prometheus 效果

 

• granfana dashborad 的參數效果

 

• 簡單說明
  由於測試上的很隨意其實是有問題的，可是zulu 優化上的openjdk 整體仍是很不錯的,鏈接有一篇別人的測試，能夠參考，可是也是不完備的。
