I have SunOS 5.10 sparc server. I want to calculate buffer memory

Question

I have SunOS 5.10 sparc server. I want to calculate buffer memory. I can easily find this in Linux using /usr/bin/free command.

             total       used       free     shared    buffers     cached
Mem:      8004388    7427228     577160          0     472196    3336544
-/+ buffers/cache:   3618488    4385900
Swap:     11534628          0   11534628

Can anyone please suggest me if there is any equivalent command in SunOS. It would be better if anyone can give me any Perl script to find the same in below format.

I am not able to get buffer memory wit sar. I tried all the options with sar.do you have anything specific that i can give a try? — user95535, Oct 15 '14 at 21:54
@Xavier Lucas Sar -r print freemem and freeswap not the buffer memory. 15:04:57 freemem freeswap 15:05:02 97809 3472239 15:05:07 97711 3468778 15:05:12 97906 3475708 — user95535, Oct 15 '14 at 22:05
@user95535 Then there's no such thing on SunOS and it's reported as free memory. — Xavier Lucas, Oct 15 '14 at 22:16
