[SNMP4J] FW: Need Help

[Ashish Kumar Maheshwari]

Hi,
      Thanks for your kind help.

Is there is any class in the SNMP4j that can combined all the hosts and then we can send the traps to the multiple host.
Right now I am using the following code,

            Address targetAddress = GenericAddress.parse(addressStr); addressStr that contains the host IP address
            TransportMapping transport = new DefaultUdpTransportMapping();
            Snmp snmp = new Snmp(transport);
            CommunityTarget target = new CommunityTarget();
            target.setCommunity(new OctetString(communityNameStr));
            target.setAddress(targetAddress);
            target.setRetries(retriesInt);
            target.setTimeout(timeoutLong);
            target.setVersion(SnmpConstants.version1);

Is any method is provided in the Address class to support the multiple host IP address , so that in a single line of code
SNMP Traps can be send on the multiple host.

Any suggestions are highly appreciated.

Needless to mention your help in this regard is highly valuable.

Thanks
Ashish

Hi,

I'm not sure for SNMP v1, but in version 2c you just need to create multiple instances of CommunityTarget class and then you can use these instances to send alarms

I hope the following example will help:

UdpAddress managerUdpAddress = new UdpAddress(InetAddress.getByName("127.0.0.1"), 162);

CommunityTarget communityTarget = new CommunityTarget(managerUdpAddress,
snmpAlarmConfiguration.getCommunityName());
communityTarget.setVersion(SnmpConstants.version2c);
communityTarget.setRetries(1);
communityTarget.setTimeout(500);

And then you can send alarm:

PDU trapPdu = new PDU();
trapPdu.setType(PDU.TRAP);
trapPdu.add(new VariableBinding(new OID(SYS_UP_TIME), new TimeTicks(sysUpTime)));
trapPdu.add(new VariableBinding(new OID(SNMP_TRAP_OID), alarmOID));
trapPdu.add(new VariableBinding(alarmOID, new Integer32(alarmSeverity)));

snmp.notify(trapPdu, communityTarget);


Best regards
