Example

Goal

You'd like to find out the pageCounters of some printers in your network.

JUnit TestCase

  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

   printer1     46592 pages
   printer2     35713 pages
   printer3     16905 pages

Explanation

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.
