cpu, memory, and hard disk information displayed by the php probe (recommended learning: PHP Programming from entry to proficiency)

The reasons why the general php probe does not display the above information are as follows:

1, Proc directory permissions

See what the permissions of the proc directory are? You can try to set the permissions of the proc directory to the default 0555

2, apache's open_basedir setting

If you turn on the open_basedir security setting, the probe will not be able to display the memory Waiting for information

3, the corresponding php function is prohibited

such as file or other functions

4, the virtual host panel is automatically set

Some panels, such as directadmin or kloxo, will also be unable to view probe information.
