Aside from the bless issue everyone else spotted (but I would have TOTALLY missed), isn't there something strange going on here?
our $curl="/usr/bin/curl -G 'http://localhost:8080/v3";
# ...
sub getHosts {
my $self = shift;
my $cmd=sprintf("%s/nodes 2>/dev/null",$curl);
Aren't you going to wind up with a mismatched single quote in $cmd if 'getHosts' gets called? 'getHostsFacts' does it right, it looks like...

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).
