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.
1. Make sure that an operating system meets Plesk CGroups extension requirements.
2. In order to install CGroups open Tools & Settings > Updates > Add/Remove Components > Resource controller (Cgroups).
3. After that start the extension in Tools & Settings > Services Management > Resource Controller (Cgroups).
