• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Plesk Monitoring Disk Threshold Alerts Wrong

Windows Server 2022
Plesk version and microupdate number
18.0.80 #6
The monitoring threshold on Windows servers is generating disk usage alerts even when actual disk utilization is well below the configured threshold.

For example, the threshold is set to 95%, but alerts are being triggered when disk usage is only around 88%.

This was an issue a month or so ago that I thought had been addressed, but it appears to still be occurring. It’s also possible that a recent update has reintroduced the problem.

Is anyone else seeing this behavior on Windows servers?
