To add a Beanshell Sampler in Apache JMeter, you can follow these steps:

1. Open your JMeter test plan.
2. Right-click on the test plan, then go to "Add" > "Sampler" > "Beanshell Sampler".
3. Enter the Beanshell script in the "Script" section. You can write your Java or Beanshell code here.
4. If needed, you can set up the variables in the "Variables" section to be used in your script.
5. You can also configure the "BeanShell Preprocessor" if needed.
6. Finally, run your test and view the results in the "View Results Tree" listener.

Note: Beanshell Sampler can slow down your test execution, so it's recommended to use it carefully and only when it's necessary.

Here is an example of how you can add a Beanshell Sampler in JMeter:

1. Open your JMeter test plan.
2. Right-click on the test plan, then go to "Add" > "Sampler" > "Beanshell Sampler".
3. In the Beanshell Sampler GUI, you will see a text area where you can enter your Beanshell script.
4. Write your Beanshell script in the text area. For example, you can use the following script to print "Hello, JMeter!" to the console: log.info("Hello, JMeter!");
5. Optionally, you can set up variables in the "Parameters" section. This will allow you to use these variables in your script. For example, you can set a variable named "name" with the value "JMeter" and use it in your script like this: String name = ""; log.info("Hello, " + name + "!");
6. You can also configure the "BeanShell Preprocessor" if needed. This allows you to execute a Beanshell script before the sampler runs.
7. Once you have written your script and configured the necessary options, you can run your test and view the results in the "View Results Tree" listener.

That's it! You have successfully added a Beanshell Sampler in JMeter.
