• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey.

  • 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.

Issue cgroups monitoring: Strange “gaps” in graphs

Hi,

I have an issue with the graphs that are generated by Grafana.
The global server graphs in the monitoring extension are just fine, but the subscriptions graphs have gaps in it. It's not just this server, other servers have the same issues.

This is the graph of one of the subscriptions:

This is the data that Grafana collects:

What's going on here?
There is no relation with the load on the server.
Latest update of RRDTools didn't make a difference.

CentOS Linux 7.9.2009 (Core) / Plesk Obsidian Version 18.0.42
