Obtain Memory on HP UNIX
Hi,
Does anyone know an easy way of getting the memory usage on a UNIX box? I basically want to find the total % available/in use. Running vmstat gives me 'avm' and 'free' but come in bytes and not percents. Didn't see a switch in sar that just gave me the memory stats similar to Sun's -r command. Oh, and I need it to come one one line (like sar or vmstat). Cheers, J

Glance PLUS is going to do what you need, but you'll have to pay for it depending of the version of HP-UX you have. I know that it comes with the Enterprise OE version of HP-UX but you have to buy a pack for Foundation OE version.
Code:
GlancePlus C.03.85.00 09:51:39 xxxx ia64 Current Avg High

PxT pioneered a technique involving invoking pstat from perl. I have been studying the technique in preparation for a script I plan to write. I have tried to write a script to solve your requirement. I may have succeeded. I have only tested it on one system. The total physical memory matches what I from cstm. Free memory matches what I get from vmstat. And the percentages match what I get from glance. So it may be working. But no guarantees.
 Code:
#!/usr/contrib/bin/perl
local($PSTAT, $PSTAT_STATIC, $PSTAT_DYNAMIC) = (239, 2, 3);
local($struct_pst) = ("\0" x 156);
local($struct_psd) = ("\0" x 2904);
syscall($PSTAT, $PSTAT_STATIC, $struct_pst, length($struct_pst), 1, 0);
($pages, $psize) = (unpack("x16LL", $struct_pst));
syscall($PSTAT, $PSTAT_DYNAMIC, $struct_psd, length($struct_psd), 1, 0);
$free = unpack("x64L", $struct_psd);
$mb = ($psize / 1024) * $pages;
$mb = $mb / 1024;
print "Physical Memory: ",$mb,"MB\n";
print "Free Pages: ", $free, "\n";
$pcfree = 100. * $free /$pages;
$pcused = 100. - $pcfree;
printf(" %0.2f%% free %0.2f%% used \n", $pcfree, $pcused);
exit 0;
