Hi,
I am a student and trying to develop a network monitoring system using Snmp and Aglets. I have downloaded the Adventnet Snmp API4. I am able to run the SnmpGet program successfully. I tried to query the OID ".1.3.6.1.2.1.2.2.1.16.2". I got some counter value.

My question is How can i get the value in bytes? It will be very useful if u can provide me with a code snippet. and also where to put the code snippet in my program.

for example in this statement SnmpOID oid = new SnmpOID(".1.3.6.1.2.1.2.2.1.16.2");
can i divide the value of OID that is the COUNTER value by 8. Is it poible to do that?
Please help me.

The main thing i want to do is perform this operation:

((ifInOctetsy � ifInOctetsx) + ( ifOutOctetsy � ifOutOctetsy))*8
U(t) = ----------------------------------------------------------------------------
(y-x)*ifSpeed

Please help in this regard.

If the information provided is confusing please tell me, I'll explain the things in a better way.


Here is the program i used to query the OID:.1.3.6.1.2.1.2.2.1.16.2

package examples.traffic;

import java.net.*;
import com.ibm.aglet.QoC;
import com.ibm.aglet.Aglet;
import com.ibm.aglet.Ticket;
import com.ibm.aglet.*;
import com.adventnet.snmp.beans.*;
import com.adventnet.snmp.snmp2.*;
import com.ibm.aglet.event.MobilityAdapter;
import java.awt.*;


public class traffic extends Aglet
{

public traffic()
{
}

@Override
public void onCreation(Object init)
{
addMobilityListener(new MobilityAdapter());

System.out.println("Initiatizing...");

}
@Override
public void run()
{


SnmpAPI api;
api = new SnmpAPI();
api.setDebug(true);
api.start();

SnmpSession session = new SnmpSession(api);


// open session for use by the applet

try {
session.open();
} catch (SnmpException e ) {
System.err.println("Error opening socket: "+e);
}

// set remote host - make sure your agent is running


// add OID
SnmpOID oid = new SnmpOID(".1.3.6.1.2.1.2.2.1.16.2");

// build GET request
SnmpPDU pdu = new SnmpPDU();


UDPProtocolOptions opt = (UDPProtocolOptions)session.getProtocolOptions();//new UDPProtocolOptions();
opt.setRemoteHost("172.1.3.107");

pdu.setProtocolOptions(opt);

pdu.setCommand( SnmpAPI.GET_REQ_MSG );
pdu.addNull(oid);


try {


pdu = session.syncSend(pdu);
} catch (SnmpException e) {
System.err.println("Error sending SNMP request: "+e);
}


if(pdu==null)

{System.out.println("Return NULL"+pdu.getError());


}
else System.out.println(pdu.printVarBinds());

setText(pdu.printVarBinds());

// print the response pdu



// close session
session.close();

// stop api thread
api.close();

}
}
