sg_get_page_stats, sg_get_page_stats_diff — get paging statistics

Synopsis

#include <statgrab.h>

sg_page_stats *sg_get_page_stats();

sg_page_stats *sg_get_page_stats_diff();

Description

sg_get_page_stats and sg_get_page_stats_diff both return a pointer to a static buffer of type sg_page_stats.

sg_get_page_stats will return the number of pages the system has paged in and out since bootup. sg_get_page_stats_diff will return the difference since last time it was called. If it has not been called before, it will return sg_get_page_stats.

Return Values

typedef struct{
        long long pages_pagein;
        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 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.
