Concurrent users of CIFS Shares over a time period

Hi All,

I have a few CIFS shares configured, I do see that the "Max Users" attribute value is set to a very high number.  

Trying to gather the average number of concurrent users over a period of time. I am running Clustered Data ONTAP 8.x and hence trying to figure out a way via CLI or ONTAPI interface so that it can be gathered programmatically or via script. Would like to monitor this info on regular basis. 

For example: On an average (or 95th percentile) how many concurrent users were seen over the last 1 week or 1 month?

Thanks in advance!
