memory listing in SAM

[Praveen Bezawada]

HI
In system properties listing in sam ,
the memory list as
1)physical memory which is the physical RAM size
2) Real Memory ???
Active ??
Free ??
3) Virtual Memory swap used + ram
Active swap active + ram
Free swap used- swap active + ram
4) Swap Size of device swap
Used used
Free used
But the size of virtual memory is less than what we get from the calculation above. What does sam actually show.

Hi

The following equations are for Active Real Memory and Total Real Memory:

Active Real Memory is computed by:

(pst_dynamic.psd_arm * pst_static.page_size * 0.000977) + 0.05

Total Real Memory is computed by:

(pst_dynamic.psd_rm * pst_static.page_size * 0.000977) + 0.05

Sam calculates the Real Memory values by calling the system commands pstat_getstatic and pstat_getdynamic. You can reference the man page for pstat_getstatic (2), pstat_getdynamic (2), and /usr/include/sys/pstat.h.
