• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

Issue High CPU usage

Having issues with high CPU usage on our server

running 2 WooCommerce sites for a few years with no issues, only way to reduce the CPU usage is to suspended the sites.
Have turned plugins off 1 by 1 but nothing changes enough to pin point what is causing the high usage.
In the process list one site list more processes than the other.
how can I work out what theses processes are liked to? I can see they all have unique PID numbers, but do not know where to look.
The screenshot percentage is with WooCommerce plugin deleted from both sites.
Any help would be greatly appreciated

Perhaps your sites are hit by more (aggressive) bots, causing a spike in CPU usage? Do you monitor traffic and checked access logs for unusual request patterns?
