Script to check whats hogging the system

,

This script takes 2 samples over a 10 second period to identify what spids are using most resources. It's probably not 100% accurate but it's helped me out a few times.

--currently has a 10 second delay but this can be changed

--retrives the current state of play from the sysprocesses table
select spid, sum(cpu) as totcpu,sum(physical_io) as totphys 
into #samp1
from master..sysprocesses
group by spid

--wait for 10 seconds

--subtract 1 from the other and find out what's going on

else (s2.totcpu - s1.totcpu)/10
end as cpusec,

where s1.spid = s2.spid
and s1.spid = sp.spid
and (s2.totcpu-s1.totcpu>1
or s2.totphys-s1.totphys>1)
order by 2 desc

--tidy up a bit
drop table #samp1
drop table #samp2
