我有一个Perl脚本,可以注册SNMP OID。使用SNMP 1 / 2c,它能够成功注册所有OID。但是,使用SNMP V3,它只能部分工作。
如下所示,使用SNMP V3,它可以成功注册“$ root_OID.0.0.0”。但是,尝试调用“$ root_OID.0.0.1”的java代码时会超时。
有谁知道,为什么我能够在SNMP V1 / 2c中成功进行java调用,而不是SNMP V3?
非常感谢
这是我的Perl脚本:
#!/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);
这是我的/etc/snmp/snmpd.conf文件(禁用SNMP V1 / 2c):
