Linux inode Disk % OID

Can anyone give me a run book on making this OID a reality?

I am not a Linux admin so I need to relay to our real Linux Admin what he needs to do on his end, I believe he needs to add this MIB to snmp.conf?

I am aware that SAM 6.3 will have this functionality (thank you AE) but I need it yesterday. And I am wondering if it can be done with the current toolset.

Thanks!
