Symptoms

When accessing the "Home / Server Status / Server Information" interface in WHM, the "Memory Information" and "Physical Disks" sections will be empty, as shown in the following image.

Description

This information is gathered from the /var/log/dmesg file on your server. In newer OS releases like CentOS 8 and AlmaLinux 8, this log file is not enabled by default. While the cPanel software will recreate this file if missing when accessing the Server Information interface, this only adds in the current dmesg utility output. If your Kernel Buffer Ring is full and has removed the memory/disk information from the logs, this section will remain empty

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-37789. Follow this article to receive an email notification when a solution is published in the product. 

 

Workaround

  1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
  2. Create the /etc/systemd/system/dmesg.service configuration file. 
    touch /etc/systemd/system/dmesg.service
  3. Open the dmesg.service file with your preferred text editor.
  4. Add the following to the file. 
    [Unit]
Description=Create /var/log/dmesg on boot
ConditionPathExists=/var/log/dmesg

[Service]
ExecStart=/usr/bin/dmesg
StandardOutput=file:/var/log/dmesg

[Install]
WantedBy=multi-user.target
  5. Create the log file. 
    touch /var/log/dmesg
  6. Enable the service to start on boot. 
    systemctl enable dmesg
  7. Reboot the server. 
    shutdown -r now
