Here is a little C program that works on Solaris:

$ sysconf
Memory->total=5120M free=1596M pct=31 pagesize=8K CPU->total=6 online=6

$ cat sysconf.c
#include <stdio.h>
#include <sys/unistd.h>

main()
{
  int wk1, wk2, wk3, wk4;
  long total_pages, free_pages, pagesize, total_cpus, total_cpus_online;

  total_pages       = sysconf(_SC_PHYS_PAGES);
  free_pages        = sysconf(_SC_AVPHYS_PAGES);
  pagesize          = sysconf(_SC_PAGESIZE);
  total_cpus        = sysconf(_SC_NPROCESSORS_CONF);
  total_cpus_online = sysconf(_SC_NPROCESSORS_ONLN);

  wk1 = (total_pages * (pagesize / 1024)) / 1024;
  wk2 = (free_pages * (pagesize / 1024)) / 1024;
  wk3 = (free_pages * 100) / total_pages;
  wk4 = (pagesize / 1024);

  printf("Memory->total=%dM free=%dM pct=%d pagesize=%dK CPU->total=%d online=%d\n",
     wk1, wk2, wk3, wk4, total_cpus, total_cpus_online );

}

Hi,

Thank you all for showing me how to check the Unix memory.  Is there a way to show how much is used and how much is free?

Thank you!

Janet
