Hi,
there you go.
i must confess that i missed also 1 thing in your sort function.
the cpu percentage will not interpreted as an numeric value, so you have to use cmp instead of <=>.
see perlop
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
my %results = (
'hostname1' => {
'1' => {
'pass' => 1,
'cpu' => '0.07%',
'box_name' => 'hostname',
'capacity' => '0.41%'
}
},
'hostname2' => {
'1' => {
'pass' => 1,
'cpu' => '0.04%',
'box_name' => 'hostname',
'capacity' => '0.25%'
}
}
);
my $results = \%results;
foreach my $router ( sort { $results->{$a}{1}{cpu} cmp $results->{$b}{
+1}{cpu} } keys %{results} ) {
print Dumper($results->{$router});
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
