No data on system resource and traffic usage

Symptoms

No data in the “System resources usage by user” and “Traffic usage” sections under any user of the panel.

Causes

There is less than 10% of free space left in the root disk partition on the server. The issue is common in Linux operating systems with kernel version below 4.15.6.

Solution

Delete any unnecessary files or expand the disk partition if possible.
The “psacct” application, which collects statistics, requires on average at least 10% free disk space to collect information to the /var/account/pacct file. After adding free space, restart the “psacct” service with the following command:

systemctl restart psacct

PLEASE NOTE!

If the kernel version of your operating system is below 4.15.6, we recommend planning a migration to an up-to-date OS from the list of supported OSes.
