Monitor CPU Usage by Query?

We are currently running MS SQL 8.0 on Windows 2003. I've been tasked
setting up a monitor that can identify queries that are causing CPU
spikes.
Does anyone have any suggestions about going about this? I'm at a
complete loss.The Profiler can do this. Create a new trace using the SQLProfilerStandard
trace template and add the CPU column. This will show both the query and the
CPU time, plus some other stuff. If this is a super busy production server
this can degrade performance so you might want to play with it on a test db
instance first. I typically run it from my desktop or from a remote desktop
and save the results to a local file cause if you write the result to the db
you are monitoring it too can impact your findings.

utility to create an alert for administrators to receive when a query

trace for CPU usage of a certain level, but I don't see how I could use
that to create an alert. Any thoughts?

lowest usage:
SELECT * FROM master..sysprocesses ORDER BY cpu DESC
Then, run this to see the actual query:
DBCC INPUTBUFFER (spid) -- spid being the # in the spid column from the
above query

own custom traces which can viewed realtime or logged to files and
replayed.

that monitors for query execution but I'm not sure of the details on how it
works.
Like the other person (tootsuite) posted you could use perfmon however it
does not take sustained thresholds, that is if CPU > 90% over 60 seconds the
n
alert. So anytime the CPU is above your threshold it will alert even if it
is a short lived spike you get alerted.
I'm not sure the context within which you want to filter the trace to
generate an alert. If you have any enterprise server monitoring tools like
ProIT, MOM or Nimbus available you could just monitor the CPU via those and
have it email your admin.
Are you hoping to find the rogue/cpu intense queries in action? Or are you
desiring to know when the CPU gets hammered so an admin can log in and kill
the offending query or find out the user running it?

queries.
Usually it works like this:
1. end users complain
2. look at overall picture using tool like perfmon or Quest Performance
Analysis, or even profiler (I find profiler to be flaky/unpredictable
at times, at least in 2000 it was terrible)
3. isolate queries using Quest based on various factors
4. most of our performance problems in the past have stemmed from
inadequate memory, which then in turns affects cpu, disk i/o, which
leads to blocking locks, etc - fortunately this has been resolved with
the purchase of higher performance servers + memory
so it's not enough to just isolate cpu performance, as many factors are
usually involved
so your cpu might be hammered, but the real underlying problem could be
lack of memory, etc but you wouldn't know that unless you can look at
all the various possible factors

was hoping to find something that could single out the individual
queries that are running to create the incident.

post.
SELECT * FROM master..sysprocesses ORDER BY cpu DESC
DBCC INPUTBUFFER (spid) -- shows query
it can't get much clearer than this - it will list processes by CPU
usage, highest to lowest, at the given point in time you run the stmt
Or you can invest in some type of monitoring tool, like Quest
(performance analysis) or some other tool that you like if you need to
examine various performance indicators - this is what I would recommend
for a long term solution
