Example[edit]
Goal[edit]
You'd like to find out the pageCounters of some printers in your network.
JUnit TestCase[edit]
String pageCount=".1.3.6.1.2.1.43.10.2.1.4.1";
String[] printers = { "printer1", "printer2", "printer3"}; // replace with your printer's hostnames
for (String printer:printers) {
SNMPSystem ss=new SNMPSystem();
ss.connect(printer);
SimpleNode snmpNode=ss.moveTo(pageCount);
if (snmpNode != null) {
String pages = snmpNode.property("value").toString();
System.out.println(String.format("%40s %8s pages", printer, pages));
}
}

}
Result[edit]
printer1 46592 pages printer2 35713 pages printer3 16905 pages
Explanation[edit]
The moveTo function will perform an SNMP walk on the given oid (and it's subtree) and make available the values converted as objects with the proper datatype.
