Server utilization

A better solution may be to store your substitution strings in a single
hash rather than in separate variables.

my %subs = (var1 => 'value1', var2 => 'value2');
s/%%(\w+)%%/$subs{$1}/g;

I think this is actually the "recommended" way.  It works fine whether
the hash is "my" or global.  I have a recollection that using the
symbolic references can also be dangerous if your input is coming from
untrusted sources (perhaps not in this simple case), whereas the hash is
safer.

I don't know of anything better than just running top (or some other
program that has the info you need) and parsing the output. "top" has a
batch mode where it will just print the info once and exit.

Sounds like a good candidate for a module!
