title: Figure out memory usage using SNMP on Windows
body: <p>Currently i use the following to figure it out:</p>
  
  <p>For total memory: </p>
  
  <pre><code>.1.3.6.1.2.1.25.2.2.0 
  </code></pre>
  
  <p>For used memory i walk the following oid (gives me usage of each process):</p>
  
  <pre><code>.1.3.6.1.2.1.25.5.1.1.2
  </code></pre>
  
  <p>and sum them all.</p>
  
  <p>However, this is very inaccurate, because it shows much less usage than if i use WMI or the performance monitor. </p>
  
  <p>Am i missing something? I do not want to use third party SNMP agents (like SNMP informant, which works correctly btw). I wanna figure it out using what's standard in windows.</p>
