NFS access report

I have already done some search on this and found below topic which is pretty close to my requirement, but there was no real solution available and the discussion was pretty old:

https://community.netapp.com/t5/Network-Storage-Protocols-Discussions/Reports-from-netgroup-exports/m-p/50752/thread-id/4651

My question is:

I have a NFS export on OnTap 7-mode as below:

/vol/test_vol     -sec=sys,rw,root=172.17.39.74

I want to know which hosts have accessed it over NFS in say last 1 month.

Is it possible at all? If yes, how?

My apologies if this question has been already asked and answered.
