I'm still rather new to the module, but how about putting in some error checking?
my ( $session, $error ) = Net::SNMP->session(
-hostname => $host,
-version => '1',
-community => $nodes{$host}->{community}, );
if ( !defined($session) ) {
printf("ERROR: sub snmp session undef\n");
}
my $num = $snmp->get_request( -varbindlist => [$rrd{$rrd}{$type}] )
if ( !defined($num) ) {
printf( "ERROR: %s.\n", $session->error );
}
Oh, and the default version for Net::SNMP is v1, so you can probably remove ( -version => '1', ) from your session.
Whip me, Beat me, Make me use Y-ModemG.

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).
