Question Different VMSTAT output on Linux and Solaris machines

Hi,
I am porting a piece of code from Solaris to Linux. Code uses VMSTAT command.
On Solaris machine VMSTAT output is following:
Code:
uname -a:
SunOS rgsm01 5.9 Generic_118558-03 sun4u sparc SUNW,Sun-Fire-V440

vmstat:
Code:
kthr memory page disk faults cpu
r b w swap free re mf pi po fr de sr m1 m2 m4 m5 in sy cs us sy id
0 0 0 29021296 3922400 177 335 27 568 380 0 3 0 0 0 0 182 293 221 32 11 57

On Linux machine VMSTAT output is following:
Code:
uname -a:
Linux GURKES060 2.6.32-279.el6.x86_64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

vmstat
Code:
procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu-----
r b swpd free buff cache si so bi bo in cs us sy id wa st
1 0 0 299732 802180 24825992 0 0 6 32 2 1 2 0 98 0 0

The paging information is there, under the "si" and "so" columns (swapped-in/swapped-out, should better be labelled "pi" and "po" for paged-in/paged-out).

Question

Thanx

---------- Post updated at 01:32 PM ---------- Previous update was at 01:20 PM ----------

But in man pages of VMSTAT on linux si and so are described as:

Code:
Swap
       si: Amount of memory swapped in from disk (/s).
       so: Amount of memory swapped to disk (/s).

However pi and po are following:
Code:
pi:    Pages paged in from the paging space. 
po:    Pages paged out to the paging space.


also I need following fields:
Code:
mf
de
sr

Linux documentation uses swap when it should use paginate, for historical reasons.

Use "sar -B interval" for more detailed statistics including faults and scan rate.
