install and configure snmp on linux

Hi,
i have a linux server with following details :
2.6.39-400.17.1.el6uek.x86_64
Oracle Linux


but i can't see any information on interfaces tab 

Unable to fetch Interfaces - Possible Reasons

  • SNMP service may not be running on the device
  • The SNMP credentials may be wrong
  • The device may not be up and running at the moment.
  • SNMP port might be blocked.









when i try to  ReDiscover Device   
there is snmp and also cli , which one should i choose? beacuse i don't have any snmp credential!
