I am facing situation where sar -u command is showing 0 for all cps, so does it mean all the cpus are fully utilized, os is oracle Linux 6.8

Code:

01:34:13 PM       all     0      0      0      0     0.00     0

What sar command are you using exactly. On my system sar -u produces a diagnostic indicating that an operand is required.

When you run sar what is the heading line in the output? On my system, the output from the command:

Code:

sar -u 1

from a few minutes ago was:

Code:

22:18:24  %usr  %nice   %sys   %idle
22:18:25    1      0      1     98
Average:      1      0      1     98

You have more output fields, than I'm seeing. My output is showing 1% of CPU being used by user code, 1% of CPU being use by system code and 98% idle. I can't guess at how the output you have shown us correlates to the output I see on my system since we can't have 0% user time, 0% system time, AND 0% idle.

I am getting below ouput , I have run only sar -u
09:40:01 AM CPU %user %nice %system %iowait %steal %idle

please suggest
