in reply to Return from a subroutine generates a negative value

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.
