Webmaster uses a CVM as a website server, and it is more difficult to guide the use and maintenance of a CVM than a virtual host. When we find that the website suddenly slows down, how can we simply check it?

Check the overall task of the CVM:

Top command

1. Check the disk capacity

If the disk is full, it will make it impossible to write to the cache, session, and so on, which in turn will cause many websites to fail to open.

The command df-h to check the disk

2. Check the available memory (display memory in MiB)

Free-m

As shown in the figure, the remaining available memory will be displayed in centos7

3. Check the server bandwidth using the iftop tool

Through the above steps, we can conduct a comprehensive check on the performance of the CVM, which can find out the reasons for the slow speed of the website.
