Perl for SNMP V3 Not Working, but works with SNMP V1/2 (Redhat Linux) - linux

Question

I have a Perl Script, which registers SNMP OIDs. With SNMP 1/2c, it is able to successfully register all OIDs. However, with SNMP V3, it only partially works.
As you see below, with SNMP V3, it is able to register "$root_OID.0.0.0" successfully. However, it timeouts when trying to invoke the java code for "$root_OID.0.0.1".
Does anyone know, why I'm able to make a successful java call in SNMP V1/2c, but not SNMP V3?
Many Thanks
Here is my Perl script:
#!/usr/bin/perl
use NetSNMP::OID (':all');
use NetSNMP::ASN qw(ASN_OCTET_STR ASN_INTEGER);
use NetSNMP::agent (':all');
sub myhandler {
my ($handler, $registration_info, $request_info, $requests) = #_;
my $request;
my $root_OID = ".1.3.6.1.4.1.8072.9999.9999.0";
my $CLASSPATH = "/opt/BPL/JBoss/BPL_JBossJMX.jar:/opt/jboss-5.1/client/*";
my $CLASSNAME = "com.XXXXX.XXXXX.XXXXX.jmx.BPLJbossJMX_For_SNMP";
my $ENV = "localhost";
my $PORT = "8099";
my $LOG4JFILELOC = "/opt/BPL/JBoss/JBoss-BPL-Log4j.xml";
for($request = $requests; $request; $request = $request->next()) {
my $oid = $request->getOID();
if ($request_info->getMode() == MODE_GETNEXT) {
if ($oid < new NetSNMP::OID("$root_OID.0.0.0")) {
my $INPUTSTRNAME = "HeapMemoryUsageZZZZZ";
$request->setOID("$root_OID.0.0.0");
$request->setValue(ASN_OCTET_STR, $INPUTSTRNAME);
} elsif ($oid < new NetSNMP::OID("$root_OID.0.0.1")) {
my $INPUTSTRNAME = "HeapMemoryUsage";
my $OUTPUT= `java -cp $CLASSPATH $CLASSNAME $ENV $PORT $INPUTSTRNAME $LOG4JFILELOC`;
chomp($OUTPUT);
$request->setOID("$root_OID.0.0.1");
$request->setValue(ASN_INTEGER, $OUTPUT);
}
}
}
}
my $rootOID = ".1.3.6.1.4.1.8072.9999.9999.0";
my $regoid = new NetSNMP::OID($rootOID);
$agent->register("BPL-JBoss", $regoid, \&myhandler);
Here is my /etc/snmp/snmpd.conf file (SNMP V1/2c disabled):
