• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

At least, the graph says that need to look a little bit deeper to understand what generates the usage: is it legitimate usage and maybe need to upgrade the server hardware? is some website poorly written? is there some virus generating usage?

  • With the Monitoring extension, you can check all rest tabs to find more clues on what could generate CPU usage (the "Services" tab).
  • Also with the Monitoring extension (the "Settings" button on the Monitoring extension page), if your system supports cgroups feature, it is possible to start monitoring subscriptions usage. If the issue with a subscription, it could help to find out which one,
