To get the physical memory from Unix:
$physical_mem = `top -d 1 | grep -i ‘Memory’ | awk ‘{ print \$2 }’ | sed -e ‘s/M//g’`;
chomp($physical_mem);
$physical_mem = int($physical_mem);

To make the script work under freebsd the os check and momory check need to be extended:

– Line 63

} elsif ($^O eq ‘freebsd’) {
$OStype = “freebsd”;

– Line 475

elsif( $OStype eq ‘freebsd’ ) {
my $sysctl = {};
my $sysctl_output = `/sbin/sysctl hw.physmem`;
$sysctl_output =~ m/^[^:]+:\s+(\d+)$/s;
$physical_mem = int($1/1024);
}

Steve,
You didn’t miss it.
I’ll be writing a second post within the week which will have the script attached. It still needs some minor changes to make it generally usable, since it was designed for our internal system. I’ll post a comment here when it’s ready.

Sorry for the inconvenience.

Where’s the download? Am I missing it?
