本部分主要对ES的一套测试流程有一个熟悉，不断分析和学习各个指标和统计方法，找到性能瓶颈

一、装备

        Linux环境

        ElasticSearch单结点，无副本单分片

        Kibana + x-pack 监控集群

        jmeter压测

        nmon监测Linux性能

 

二、服务器环境：

三、准备过程

1、elasticsearch5.4.2，kibana，x-pack

elasticsearch即插即用，下下来改改配置就能用；

kibana类似，在配置文件里修改为本地的ES地址即可；

原本是打算用marvel监控，但貌似自5.0之后的ES的HEAD啊，marvel啊这些插件全没了，全集成到x-pack里面了

elasticsearch中运行 elasticsearch-plugin install x-pack

kibana中运行kibana-plugin install x-pack（时间稍有些慢）

即把ES相关的性能图添加到kibana中

2、jmeter

jmeter是java开发的一块集成测试的软件，通过它可以构建测试用例，保存jmx测试用例并交到服务器上执行。

jmeter支持远程启动，在服务器上启动jmeter-server(可能需要参数指定ip），在本机jmeter.properites中添加remote_server:远程ip:1099（1099为默认端口），即可在jmeter运行脚本时使用远程启动。

由于服务器不在局域网内，因此上传jmx文件给服务器使用

操作：

010308_gSOD_2247638.png

右键测试计划，添加线程组，修改线程数，循环次数，运行时间等关键参数

010522_s5NA_2247638.png

在线程组中添加Sampler，选择HTTP请求

010517_qgsi_2247638.png

在HTTP请求中添加聚合报告和结果树

在文件=>保存为测试计划 中保存jmx文件

3、nmon

nmon是一款linux下的系统性能指标工具，提供CPU，内存，磁盘IO，网络等多项指标的界面化展示。

安装：

wget http://sourceforge.net/projects/nmon/files/nmon16d_x86.tar.gz

tar xvzf  nmon16d_x86.tar.gz

得到一系列nmon对应的各种版本的文件

011019_55Rt_2247638.png

找到相应的版本的nmon文件

chmod +x 赋予可执行权限

运行：

010844_azmi_2247638.png

其中每个参数可控制展示的开关，按下c,m,d,n

011137_IGT1_2247638.png

即可监控系统性能

四、开始测试
