  SQL Server Tips by Gama and Naughter

Testing the Code

The file "test.sql" in the same directory as the code has some TSQL sample code to exercise the XP. This XP is very easy to use, it has two parameters, both numeric values. The first parameter is the time interval in milliseconds for sampling and the second parameter is the output parameter, which will contain the percentage of CPU usage for that interval of time.

DECLARE @CPUUsage int
EXEC master..XP_CPUUSAGE 500, @CPUUsage OUTPUT
PRINT 'CPU Utilization is ' + CAST(@CPUUsage AS varchar) + '%'
