How does JMeter report connection timeout when monitoring Linux Server resources? jmeterlinux

Anyone who knows about performance testing knows that Jmeter can monitor the CPU, disk, and other information of the server. However, all the procedures described in this tutorial are correct. The following error message is reported during a performance test, resulting in insufficient CPU information:

I have also tried to open a port on the Linux system, and even set it to allow the local IP address to access all the ports on the Linux system. However, this problem still exists. Unfortunately, the company only has one test, and I cannot find the answer by searching for the answer on the Internet.

I finally got an answer for almost two weeks and finally solved it today. So I want to write a blog and hope to help more people.

The default port number of jmeter-server is 4444. I changed the port to 7777, and then restarted jmeter-server. When I started jmeter again, I found that the server information could be monitored. Awesome ~~ Happy
