Difference between Sar and Vmstat
I have a question regarding vmstat and sar -B. When I run vmstat , it shows value of zero for si and so parameter (under swap). But when I run sar -B, the pgpgin/s and pgpgout/s are showing values.
Si and So measure the memory being page in and page out , right? Kind of confuse here. Arent' they suppose to match the pgpgin/s and pgpgout/s shown in sar?
