- Plesk for Linux
In Plesk > example.com > Settings > CGroups Limits the following settings are set:
CPU limit set to 25%.
CPU notification threshold set to 24%
Email notification reports a subscription reached the threshold and in the notification email CPU usage for the period is much higher than set CPU limit. For example:
CONFIG_TEXT: The resource usage threshhold was reached by the subscription example.com at 05:00
CPU usage: 61% during 5 minute(s)
CPU usage notification threshold is: 24% per 5 minute(s)
Hard CPU usage limit is: 25% per 5 minute(s)
Server timezone is Europe/Helsinki (+3 GMT)
This is a Plesk bug #PPPM-8575, which will be fixed in one of the following updates.
Until fix be available incorrect statistic in the email can be safety ignored.
The issue is cosmetic and related to statistic calculation only. CGroups functionality is not affected.
