title: how to get trap messages about cpu usage using snmpd.conf
body: <p>i'm trying to create a threshold for cpu usage in snmpd.conf.</p>
  
  <p>i included the MIB in the configuration file for the cpu usage:</p>
  
  <p><em>.1.3.6.1.4.1.2021.11.10.0</em></p>
  
  <p>but i really don't know what are the flags needed for me to monitor that. 
  it is not like </p>
  
  <p><em>load 10 11 12</em>
  and how to invoke the monitor command that will send the trap message when the cpu percentage exceeds the threshold   </p>
