From the perldoc of Net::SNMP:
get_request() - send a SNMP get-request to the remote agent
$result = $session->get_request(
[-callback => sub {},] # non-blocking
[-delay => $seconds,] # non-blocking
[-contextengineid => $engine_id,] # v3
[-contextname => $name,] # v3
-varbindlist => \@oids,
);
[...]
A reference to a hash is returned in blocking mode
which contains the contents of the VarBindList.
In non-blocking mode, a true value is returned when
no error has occurred. In either mode, the undefined
value is returned when an error has occurred. The
"error()" method may be used to determine the cause
of the failure.
I see you're using 'nonblocking' mode in your call to session() so you're getting a "TRUE" value returned as per the documented operation. Try removing the '-nonblocking => 1' line from the call to session() and see what happens.

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).
