Question
How to install the Plesk Cgroups Manager resource controller in Plesk?
Answer
Note: The Plesk Cgroups Manager is not available for CloudLinux servers, because CloudLinux has its own LVE Manager feature that provides such capabilities.
Since Plesk Obsidian 18.0.41, the Cgroups Manager has become a free-to-use feature, and a default addition to the Plesk Web Pro and Web Host editions.
This means that it may already be preinstalled on your Plesk server.
The easiest way to check if it is preinstalled is to go to Plesk > Service Plans > PLAN_NAME and check if you see a RAM, CPU, Disk I/O tab:
If you need to install the Plesk Cgroups Manager, you may follow these steps:
1. Make sure that the operating system meets Plesk CGroups extension requirements
3. Go to Tools & Settings > Updates > Add/Remove Components > Resource controller (Cgroups).
3. After that start the extension in Tools & Settings > Services Management > Resource Controller (Cgroups).
1. Make sure that the operating system meets Plesk CGroups extension requirements
