Plesk for Linux
kb: technical
Symptoms
- Repair kit does not show statisctics for disk IO in Plesk on Debian 12
- 'iotop' utility does not display values for SWAPIN and IO %.
Cause
Since the release of Linux kernel 5.14, either kernel boot parameter delayacct needs to be specified or kernel.task_delayacct sysctl parameter needs to be enabled.
Resolution
Temporary Workaround:
1. Connect to the server via SSH
2. Run the following command:
# sysctl -w kernel.task_delayacct=1
to confirm the change is complete
# sysctl -n kernel.task_delayacct
To make the change permanent
To make the change permanent after the system is rebooted run the following:
# echo "kernel.task_delayacct = 1" >> /etc/sysctl.conf
# sysctl -p

Always make sure to perform these tasks during a maintenance window or a low-traffic period to minimize the impact on your services. Additionally, consider creating backups before making any significant changes to your server.
