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.
