Prstat - Average Value too high

Hi All,

Please see to the prstat o/p of one of my sun box..

Total: 1 processes, 68 lwps, load averages: 531.00, 305.18, 144.77 Check the pstack ....


As i have read in all docs , people say a value of 5 is considered high CPU usage , i don't know then how we can even relate those statement to these o/p's .. or am i missing something !!

Cheers...

Your box seems pretty loaded although that really depends on the number of CPU/cores/threads available.
On a fully populated M9000 (512 cores), that would just be a moderate load ...

What about other statistics:
Code:
vmstat 2 2
mpstat 2 2
prstat -n 10 -Z -c 1 1

Bro jlliagre,

The load is o.k now , what i was concerned it the load average value information, please read the below link ,, every where it states a load value of 5 is considered high CPU utilization, but if 5 is too high , i can't understand why i am gettimg above 500..

My box is E6900/32 CPU /262144 Megabytes RAM/Sol 10


Thanks!!

The link is addressing single CPU servers. As yours has 32 CPUs available, that rule of thumb would translates to a 160 load average.

You need to get more details to investigate further.
