The Question is:
I try to use MONITOR CLUSTER to monitor our %CPU %MEMORY and disk I/O rate ,
for both %CPU and %MEM we satisify what we gets from this command .But we
didnot know what is the exactly unit of disk i/o.
Could you please explane the exactly meaning of disk I/O operation request and
its unit.
Regards,
The Answer is :
The unit is the number of I/O requests sent to the device.
This can be more or less than you might expect, based on the
involvement of I/O caches and of the file system activity.
