用Perl语言读取网络设备SNMP信息

#!/usr/bin/perl
use strict;
use Net::SNMP;
my ($session,$error) = Net::SNMP->session(
  -hostname  => shift || '133.109.9.78',-community => shift || 'public',-port      => shift || 161 
);
if (!defined($session)) {
  printf("ERROR: %s.n",$error);
  exit 1;
}
my $sysUpTime = '1.3.6.1.2.1.1.1.0';
my $result = $session->get_request(
  -varbindlist => [$sysUpTime]
);
if (!defined($result)) {
  printf("ERROR: %s.n",$session->error);
  $session->close;
  exit 1;
}
printf("sysUpTime for host '%s' is %sn",$session->hostname,$result->{$sysUpTime} 
);
$session->close;
exit 0;
