Jmeter（一）非GUI模式压测（NON-GUI模式）结果解析TPS

非GUI模式压测（NON-GUI模式）结果解析TPS

准备工作

1. 从脚本已录制成功之后开始进行压测
2. 安装Jmeter拓展插件 查看 Transactions per Second https://jmeter-plugins.org/wiki/TransactionsPerSecond/       ←插件地址
3. 在压测前先安装 Nmon监控工具在服务器linux性能监控分析及通过nmon_analyse生成分析报表

安装 TPS教程

解压安装

将 jpgc-graphs-basic-2.0.zip 解压缩后只有一个 lib 目录，该目录下有一个 ext 文件夹和一个 jmeter-plugins-cmn-jmeter-0.3.jar 包，ext 文件夹中有 jmeter-plugins-graphs-basic-2.0.jar 和 jmeter-plugins-manager-0.10.jar 包。
将 lib 目录下的 jmeter-plugins-cmn-jmeter-0.3.jar 拷贝到 %JMeter%/lib 目录下，将 ext 目录下的 jmeter-plugins-graphs-basic-2.0.jar 和 jmeter-plugins-manager-0.10.jar 拷贝到 %JMeter%/lib/ext 目录下，重启 JMeter，发现已经支持 TPS、TRT 等视图了：

1.0.2 Load Test running

Once your Test Plan is ready, you can start your Load Test. The first step is to configure the injectors that will run JMeter, this as for any other Load Testing tool includes:

• Correct machine sizing in terms of CPU, memory and network
• OS Tuning
• Java setup: Ensure you install the latest version of Java supported by JMeter
• Correct sizing of Java Heap. By default JMeter runs with a heap of 512MB, this might not be enough for your test and depends on your test plan and number of threads you want to run

Once everything is ready, you will use Command-line mode (called Non-GUI mode) to run it for the Load Test.

Don't run load test using GUI mode !
不要使用GUI模式运行负载测试！因为GUI模式的话会占用比较大的内存空间，并发数量上不去等等的问题

Using Non-GUI mode, you can generate a CSV (or XML) file containing results and have JMeter generate an HTML report at end of Load Test. JMeter will by default provide a summary of load test while it's running.

You can also have real-time results during your test using Backend Listener.
NON-GUI模式允许得到结果后可以在后端监听器的测试期间获得实时结果。这句话如何理解呢，见上面“TPS导入解析测试报告”

Running JMeter

To run Apache JMeter in NON_GUI

直接进入脚本路径，输入 Jmeter的启动路径

        -r, --runremote
                Start remote servers (as defined in remote_hosts)
        -R, --remotestart <argument>
                Start these remote servers (overrides remote_hosts)
        -d, --homedir <argument>
                the jmeter home directory to use
        -X, --remoteexit
                Exit the remote servers at end of test (non-GUI)
        -g, --reportonly <argument>
                generate report dashboard only, from a test results file
        -e, --reportatendofloadtests
                generate report dashboard after load test
        -o, --reportoutputfolder <argument>
                output folder for report dashboard

下面我们就采用 NON_GUI模式执行脚本 如下：（每次执行脚本之前都要把jtl文件删除，report文件夹清空！不然会报错）

--------------------------------------------------

To run Apache JMeter in NON_GUI mode and generate a report at end :
Open a command prompt (or Unix shell) and type:

jmeter.bat(Windows)/jmeter.sh(Linux) -n -t test-file [-p property-file] [-l results-file] [-j log-file] -e -o [Path to o
utput folder]

--------------------------------------------------

输入以下命令直接执行录制好的脚本文件

D:\Jmeter\apache-jmeter-5.0\apache-jmeter-5.0\jm> #先进入测试脚本所在的文件目录 

D:\Jmeter\apache-jmeter-5.0\apache-jmeter-5.0\jm>jmeter -n -t Script.jmx -l result.jtl -e -o D:\Jmeter\apache-jmeter-5.0\apache-jmeter-5.0\jm\report

Script.jmx 是脚本名称

result.jtl 是压测生成的中间件，可以在jmeter中打开

D:\Jmeter\apache-jmeter-5.0\apache-jmeter-5.0\jm\report  是测试报告的路径

运行脚本进行压测

当然，在运行脚本进行压测的时候 需要在服务器 先执行 采集命令

ps -ef | grep nmon 查看采集数据的进程

[root@lamw /home/lam7/nmon]# ps -ef | grep nmon

[root@lamw /home/lam7/nmon]# nmon -f -s 1 -c 60

-f 表示生成的数据文件名中有时间；

-t 输出中包括占用率较高的进程；

-s 1 表示每 1 秒采集一次数据；

-c 60 表示采集 60 次，1s*60=60秒；

至于监控的方式可以查看上面所讲的准备工作第三点。

Apache JMeter Distributed Testing Step-by-step

This short tutorial explains how to use multiple systems to perform stress testing. Before we start, there are a couple of things to check.

• the firewalls on the systems are turned off or correct ports are opened.
• all the clients are on the same subnet.
• the server is in the same subnet, if 192.x.x.x or 10.x.x.x IP addresses are used. If the server doesn't use 192.xx or 10.xx IP address, there shouldn't be any problems.
• Make sure JMeter can access the server.
• Make sure you use the same version of JMeter and Java on all the systems. Mixing versions will not work correctly.

Once you've made sure the systems are ready, it's time to setup remote testing. The tutorial assumes you already have JMeter installed on all the systems. The way JMeter works is one master controller initiates the test on multiple slave systems.

Before we dive into the step-by-step instructions, it's a good idea to define the terms and make sure the definition is clear.

Master

the system running JMeter GUI, which controls the test

Slave

the system running jmeter-server, which takes commands from the GUI and send requests to the target system(s)

Target

the webserver we plan to stress test

1. On the slave systems, go to jmeter/bin directory and execute jmeter-server.bat(jmeter-server on unix).
2. On master system acting as the console, open windows explorer and go to jmeter/bin directory
3. Open jmeter.properties in a text editor
4. Edit the line remote_hosts=127.0.0.1
5. Add the IP address. For example, if I have JMeter server running on 192.168.30.50:1099, …, 192.168.30.51:1099,the entry would like like this

:

1. Start JMeter.
2. Open the test plan you want to use

Start a single clients

1. Click Run at the top
2. Select Remote Start
3. Select the IP address

Start all clients

1. Click Run at the top
2. Select Remote Start all or use Ctrl + Shift + R

Limitations

There are some basic limitations for distributed testing. Here's the list of the known items in no specific order.

1. RMI cannot communicate across subnets without a proxy; therefore neither can JMeter without a proxy.
2. Since version 2.9, JMeter sends all the test results stripping Response data to the controlling console, this allows us to reduce impact on network IO. Ensure you monitor your network traffic so that this trafic does not incur contention
3. A single JMeter client running on a 2-3 GHz CPU (recent CPU) can handle 1000-2000 threads depending on the type of test.

简单点的说

Jmeter分布式执行原理：

　　1、Jmeter分布式测试时，选择其中一台作为调度机(master)，其它机器做为执行机(slave)。

　　2、执行时，master会把脚本发送到每台slave上，slave 拿到脚本后就开始执行，slave执行时不需要启动GUI，我理解它应该是通过命令行模式执行的。

　　3、执行完成后，slave会把结果回传给master，master会收集所有slave的信息并汇总。

术语解析

• master，以GUI模式运行，同时控制测试的运行，在这里就是client，启动脚本所在的那台机器。
• slave，运行jmeter-server并从master接收指令、向目标服务器发送请求

• 设置jmeter-server:

  用文本编辑器打开Jmeter/bin目录下的jmeter.properties文件，添加运行jmeter-server的主机IP到remote_hosts

remote_hosts=192.168.30.50:1099,192.168.30.51:1099,localhost.....

小白解释分割线

----------------------------------------------------------

再白痴点的解释就是   有 A B C  三台压力机器，属于同一个内网IP

A作为 Master

B跟C两台作为slave

通过A去控制B跟C进行压测服务器
在压测的过程中 需要先开启B跟C的Jmeter的bin目录下的jmeter-server.bat 服务

然后通过A去进行NON-GUI模式去压测，B跟C分布式的压测结果会反馈到A

-----------------------------------------------------------

小白解释结束线

下面进行实战命令 压测

        -n, --nongui
                run JMeter in nongui mode
        -s, --server
                run the JMeter server
        -H, --proxyHost <argument>

        -G, --globalproperty <argument>=<value>
                Define Global properties (sent to servers)
                e.g. -Gport=123
                 or -Gglobal.properties
        -D, --systemproperty <argument>=<value>
                Define additional system properties
        -S, --systemPropertyFile <argument>
                additional system property file(s)
        -L, --loglevel <argument>=<value>
                [category=]level e.g. jorphan=INFO or jmeter.util=DEBUG
        -r, --runremote
                Start remote servers (as defined in remote_hosts)
        -R, --remotestart <argument>
                Start these remote servers (overrides remote_hosts)
        -d, --homedir <argument>
                the jmeter home directory to use
        -X, --remoteexit
                Exit the remote servers at end of test (non-GUI)
        -g, --reportonly <argument>
                generate report dashboard only, from a test results file
        -e, --reportatendofloadtests
                generate report dashboard after load test
        -o, --reportoutputfolder <argument>
                output folder for report dashboard

Error: Missing argument to option -l

其中

-r, --runremote    

Start remote servers (as defined in remote_hosts)------------------启动远程服务器（如remote_hosts中定义）
-R, --remotestart <argument>
Start these remote servers (overrides remote_hosts)-------------------启动这些远程服务器（覆盖remote_hosts）

那么我们就可以去选择执行所有的配置中的压测机器

D:\Jmeter\jmeter-3.1\bin\jmeter.bat -n -r -t test.jmx -l test.csv -e -o test

可以看到已经成功执行了配置中的2台压测机

PS 如果压测指标是1000并发数，比如我们现在配置了2台需要达到1000并发数，那么就是一台压测并发数500即可
