sg_get_page_stats(3)                                      sg_get_page_stats(3)



NAME
       sg_get_page_stats,     sg_get_page_stats_r,     sg_get_page_stats_diff,
       sg_get_page_stats_diff_between, sg_free_page_stats - get paging statis‐
       tics

SYNOPSIS
       #include <statgrab.h>


       sg_page_stats *sg_get_page_stats (size_t *entries);

       sg_page_stats *sg_get_page_stats_r (size_t *entries);

       sg_page_stats *sg_get_page_stats_diff (size_t *entries);

       sg_page_stats *sg_get_page_stats_diff_between (const sg_page_stats
                       *cur, const sg_page_stats *last, size_t *entries);

       sg_error sg_free_page_stats (sg_page_stats *data);

DESCRIPTION
       The page stats module deliver the number of pages swapped in  and  out,
       either  since  the  machine has been booted (by the sg_get_page_stats()
       and sg_get_page_stats_r() functions) or the difference between two mea‐
       sured     statistics     (by     the    sg_get_page_stats_diff()    and
       sg_get_page_stats_diff_between() functions).

       The sg_get_page_stats_diff() function calculates the difference between
       the  last  call to the function sg_get_page_stats() in this thread (the
       statistics of the earlier call are  saved  and  sg_get_page_stats()  is
       called immediately after this).

       API Shortcut

       allbox  ; l | l | l.  T{ function T}   T{ returns T}   T{ data owner T}
       l | l | l.  T{ sg_get_page_stats T}   T{ sg_page_stats *  T}   T{  lib‐
       statgrab (thread local) T} T{ sg_get_page_stats_r T}   T{ sg_page_stats
       * T}   T{ caller T} T{ sg_get_page_stats_diff T}   T{  sg_page_stats  *
       T}   T{ libstatgrab (thread local) T} T{ sg_get_page_stats_diff_between
       T}   T{ sg_page_stats * T}   T{ caller T}

       The sg_page_stats buffer received from  sg_get_page_stats_r()  and  the
       sg_get_page_stats_diff_between()      must      be      freed     using
       sg_free_page_stats() when not needed any more. The caller is  responsi‐
       ble for doing it.

RETURN VALUES
       typedef struct{
               unsigned long long pages_pagein;
               unsigned long long pages_pageout;
               time_t systime;
       }sg_page_stats;


       pages_pagein
              The number of pages swapped into memory.

       pages_pageout
              The number of pages swapped out of memory (to swap).

       systime
              The  timestamp  when  the above stats where collected in seconds
              since epoch or the  time  period  over  which  pages_pagein  and
              pages_pageout were transferred.

BUGS
       Solaris  doesn't  seem  to  report accurately. It reports the number of
       pages swapped into memory, not  necessarily  from  swap.  This  feature
       isn't deemed entirely reliable.
