How to monitor server,s system performance while running Jmeter

This is the big question , when you are putting load on webserver from your computer or using distributed load testing, what is behaviour of server's computer..Server's computer behaviour means at the time of load what is cpu performane, network performance, i/o. So we need to monitor thise things also. But as i have practiced i was not be able to do distributed load testing and also monitoring the cpu performane of server's computer. For that what you can do?I will tell you waht i have tried. I open two jmeter windows. In one window i did distributed load testing, and in another i used the same script but with single thread (user), and check on forever, and added the server performance monitor listners. What it will do? It will run one user in loop till you will not stop the test and also provide you the server's computer performance. Because one user will create that much diffreence according to me.
First i will tell you have to add plugins in jmeter for listners.

For that you have to download  jmeter plugin.jar for the jmeter version you are using. Now extract jmeter plugin and copy jmeter plugin.jar file to c:/jmeter/lib/ext. And from the extracted file you will also get the server agent folder. Copy the server agent folder to the web server's computer and past it in c: drive. Explore server agent folder at server's end and start start agent.bat file.

Now you should know the server's computer ip. Like we have the server ip is 192.168.45.89.

Now from your computer start jmeter and add-:

After clicking server performance monitor you will see the window like:-

In this window you will be able to see add row,copy row and delete row.And clickig on add row the window will be like:-

Here below Host/Ip where local host is written you have to type the ip of server's computer.And the port will be by default set to 4444 till no changes done at the server end.

Also you will be able to see cpu,memory,swap,disksI/O,NetworksI/O.From here you can select single object at a time.If you want to see all the details at the same time,so you can add server performance monitor from thread group-add-listners,and then can select another object.

Remember first you have to record or open the test then add the listners.

Now when you will start the test you will be able to see the server's performance selecting server performance monitor.

I think this blog may helpful to you for this senario..

Thank you
