title: SNMP OID for network traffic
body: <p>i'm working on a script that will monitor traffic on specific hosts from nagios. I have studied some scripts already made and have gathered almost all the info i need to do it but i have encountered a problem in identifying the OID's necessary for the traffic. I wanted to use <code>IF-MIB::ifOutOctets.1</code> and <code>IF-MIB::ifInOctets.1</code> to get the incoming and outgoing traffic but when i tested with the following line:</p>
  
  <pre><code>snmpwalk -v 1 -c public myComputer OID
  </code></pre>
  
  <p>i got the same result for both the OID's and that doesn't seem right. I'm wandering if there are other variables i could try instead of those i'm using now.</p>
  
  <p>It would be useful even if you can point me to where i could find some info on the <code>IF-MIB</code>, because i can get all the values with <code>snmpwalk</code> but i don't know how to interpret them</p>
