Users complain that system performance is unacceptable when using a specific application
service running on a multiprocessor service. You have established from the storage team
that disk response times have not increased, so you can discount there being an I/O
problem. You run vmstat to look at CPU activity and notice high average disk times on the
multiprocessor system and an average run queue of zero. You require more detail about
each CPU from which the vmstat figures are derived, to investigate if the load is distributed
evenly across all CPUs. Which three commands provide more detailed information about
CPU load distribution?
A.
iostat –x
B.
top
C.
mpstat
D.
vmstat
E.
