MSSQL on Windows: DB Engine CPU Utilization (\%)

Microsoft.SQLServer.Windows.CollectionRule.DBEngine.CPUUtilization (Rule)

MSSQL on Windows DB Engine CPU Utilization (\%) performance collection rule.

Knowledge Base article:

Summary

MSSQL on Windows: DB Engine CPU Utilization (%)

System CPU usage by DB Engine instance.

Percentage of CPU utilization depends on the processors affinity mask is set for the SQL Server instance. If the affinity mask is set automatically for all processors, the accumulated value will be counted with consideration for all processors’ cores according to the SQL Server edition.

Note that the running interval of the rule must not be less than 60 seconds and divisible by 60. Otherwise, the data returned by the rule will be inexact.
