Hi..
How to find out cpu utilization percentage of each instance of sql server ? suppose if have five instance in the server now i want to check the cpu utilization of each instance.
Thanks in Advance.

Use perfmon. Under the Process object you will be able to select sqlservr, sqlservr#1 etc. Then select the % Processor Time

Yes.. it is there the object in name of Processor and also the object counter %processor, it helps to find out the total CPU utilization of the server not for each sql server instance. Example if i have three instance A,B,C then i have to find the CPU utilization A ,CPU utilization B and CPU utilization C.

No, it should give you the % per process per instance.

Yes..its there in the name of sqlservr , sql servr#1. but how i can identify the name of the name of the instance from this ?

I grabbed this from an earlier post by someone else, but I've forgotten who the original poster was.
You can run the following on each instance periodically to view recent CPU history of the specific instance and the combined usage of all other processes on the server. Merge the results elsewhere to compare usage by multiple instances on a server (and store all the results in a table to look for high-use/low-use patters in each instance, etc.):
DECLARE @ts_now BIGINT
SELECT @ts_now = cpu_ticks / CONVERT(FLOAT, cpu_ticks_in_ms) FROM sys.dm_os_sys_info
SELECT record_id,
DATEADD(ms, -1 * (@ts_now - [timestamp]), GETDATE()) AS EventTime,
SQLProcessUtilization,
SystemIdle,
100 - SystemIdle - SQLProcessUtilization AS OtherProcessUtilization
FROM (
SELECT
record.value('(./Record/@id)[1]', 'int') AS record_id,
record.value('(./Record/SchedulerMonitorEvent/SystemHealth/SystemIdle)[1]', 'int') AS SystemIdle,
record.value('(./Record/SchedulerMonitorEvent/SystemHealth/ProcessUtilization)[1]', 'int') AS SQLProcessUtilization,
TIMESTAMP
FROM (
SELECT TIMESTAMP, CONVERT(XML, record) AS record
FROM sys.dm_os_ring_buffers
WHERE ring_buffer_type = N'RING_BUFFER_SCHEDULER_MONITOR'
AND record LIKE '% %') AS x
) AS y
ORDER BY record_id DESC

Read -->http://sqlserverpedia.com/blog/sql-server-bloggers/identifying-the-high-cpu-sql-instance/
and you will get to know howto link them with correct instances using process ID.
