title: How can I find what is OID for cpu usage in windows 7?
body: <p>I have a vm with windows 7. I have installed windows snmp agent service.
  Then from my pc I have developed a small program in C# to communicate with SNMP agent using <a href="http://www.snmpsharpnet.com/" rel="nofollow">snmpsharpnet</a> and works!</p>
  
  <p>I used some sample OIDs like:</p>
  
  <ul>
  <li>.1.3.6.1.2.1.1.1.0 to get system description</li>
  <li>.1.3.6.1.2.1.25.1.6. to get number of processes</li>
  </ul>
  
  <p>So my program works and I have correct network connectivity.</p>
  
  <pre><code>        string host = "192.168.1.92";
          string community = "public";
          SimpleSnmp snmp = new SimpleSnmp(host, community);
  
          if (!snmp.Valid)
          {
              Console.WriteLine("SNMP agent host name/ip address is invalid.");
              return;
          }
          Dictionary&lt;Oid, AsnType&gt; result = snmp.Get(SnmpVersion.Ver1, new string[] { ".1.3.6.1.2.1.25.3.3.1.2" }); 
  
          if (result == null)
          {
              Console.WriteLine("No results received.");
              Console.ReadKey();
              return;
          }
  
          foreach (KeyValuePair&lt;Oid, AsnType&gt;  kvp in result)
          {
              Console.WriteLine("{0}: {1} {2}", kvp.Key.ToString(),
                                    SnmpConstants.GetTypeName(kvp.Value.Type),
                                    kvp.Value.ToString());
          }
          Console.ReadKey();
      }
  </code></pre>
  
  <p>Now I am trying to get cpu load using <strong>.1.3.6.1.2.1.25.3.3.1.2</strong> but I doen't work (got info from <a href="http://forums.manageengine.com/topic/finding-cpu-mem-utilization-for-windows-system" rel="nofollow">here</a>). I have also installed a Mib Browser (from <a href="http://www.ireasoning.com/" rel="nofollow">ireasoning.com</a>) to learn correct OIDs.</p>
  
  <p>My questions are:</p>
  
  <ul>
  <li><p>Which is correct OID to get CPU Load from windows 7?</p></li>
  <li><p>OID are not common for all systems, aren't them? I mean linux, windows, routers have their own OIDs? </p></li>
  <li><p>Where can I find OIDs for windows 7?</p></li>
  </ul>
