如何从APACHE JMETER执行Linux命令或shell脚本

Do anyone know how to execute linux commands from Jmeter? I found this link online http://www.technix.in/execute-linux-command-shell-script-apache-jmeter/ and I tried the steps, but is not working. I can't see the SSH Sampler. If anyone had any success with running shell scripts from Jmeter please share. Thanks in advance

有谁知道如何从Jmeter执行linux命令?我在网上找到了这个链接http://www.technix.in/execute-linux-command-shell-script-apache-jmeter/我尝试了这些步骤,但是没有用。我看不到SSH采样器。如果有人从Jmeter运行shell脚本取得任何成功,请分享。提前致谢

Have a look at OS Process Sampler which is done for this and available in core:

看一下为此完成的OS Process Sampler并在核心中提供:

• http://jmeter.apache.org/usermanual/component_reference.html#OS_Process_Sampler

#2

If you need to execute a command on remote system take the following steps:

如果需要在远程系统上执行命令,请执行以下步骤:

1. Download JSch.jar - the library which provides SSH and SCP protocols operations from Java language and place it to /lib folder of your JMeter installation

下载JSch.jar - 从Java语言提供SSH和SCP协议操作的库,并将其放到JMeter安装的/ lib文件夹中

2. Download groovy-all.jar - Groovy scripting engine support for Jmeter and drop it to the /lib folder as well

下载groovy-all.jar - 对Jmeter的Groovy脚本引擎支持并将其放到/ lib文件夹中

3. Restart JMeter to pick the libraries up

重新启动JMeter以选择库

4. Add JSR223 Sampler to your Test Plan and choose "groovy" from "Language" drop-down

将JSR223 Sampler添加到您的测试计划中,然后从“语言”下拉菜单中选择“groovy”

5. Follow example code from Exec.java Jsch tutorial to implement your own logic.

按照Exec.java Jsch教程中的示例代码实现您自己的逻辑。

You can also refer to below snippet which executes ls command on a remote *nix system and returns command execution result. Make sure that you provide valid username, hostname and password in order so sampler could work

您还可以参考下面的代码片段,它在远程* nix系统上执行ls命令并返回命令执行结果。确保您提供有效的用户名,主机名和密码,以便采样器可以正常工作

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

JSch jSch = new JSch();
Session session = jSch.getSession("username", "hostname", 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("password");
session.connect();

Channel channel = session.openChannel("exec");

String command = "ls";
((ChannelExec) channel).setCommand(command);
channel.setInputStream(null);
((ChannelExec) channel).setErrStream(System.err);
InputStream in = channel.getInputStream();

channel.connect();
StringBuilder rv = new StringBuilder();
rv.append("New system date: ");
byte[] tmp = new byte[1024];
while (true) {
  while (in.available() > 0) {
      int i = in.read(tmp, 0, 1024);
      if (i < 0) break;
      rv.append(new String(tmp, 0, i));
  }
  if (channel.isClosed()) {
      break;
  }
  try {
      Thread.sleep(100);
  } catch (Exception ee) {
      ee.printStackTrace();
  }
}
in.close();
channel.disconnect();
session.disconnect();        
SampleResult.setResponseData(rv.toString().getBytes());

You can use the Beanshell scripting inside jmeter then you can have some thing like that:

你可以在jmeter里面使用Beanshell脚本,那么你可以有类似的东西:

    String command="your command here";
    StringBuffer output = new StringBuffer();

    Process p;
    try {
        p = Runtime.getRuntime().exec(command);
        p.waitFor();
        BufferedReader reader = 
                        new BufferedReader(new InputStreamReader(p.getInputStream()));

                    String line = "";           
        while ((line = reader.readLine())!= null) {
            output.append(line + "\n");
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    log.inf(output.toString());

Look here this answer about execute jar-file. But idea the same for other OS-command.

看看这个关于执行jar文件的答案。但对其他OS命令也一样。

1. Use OS_Process_Sampler
2. Fill field command with OS shell, like /bin/bash or analogue.

使用OS shell填充字段命令,例如/ bin / bash或analogue。

3. Set first argument with -c

用-c设置第一个参数

4. Set next argument with you command

使用you命令设置下一个参数

5. Sampler ready to execute :)

采样器准备执行:)
