I'm trying to get a better handle on this cool feature that will automatically collect NAS client statistics based on performance events.
This feature is enabled at the CLI to AUTOMATICALLY gather (you can ad-hoc gather whenever you choose). But what about the other options here. Do these options decide when the automatic gathering starts, or do something else?

Automatic collection of client statistics is based on the values of the following global options:
There are two sets of thresholds based on the above values:

In a similar way to automatic client statistics has Netapp considered adding a function to Oncommand where when a threshold is breached for one of the counters mentioned in your post it captures a perfstat for a short period?
For example if a Filers breaches the clientStatCifsLatency threshold a perfstat is captured for the Filer for a short time?
With intermittent performance issues Netapp Support often ask for a perfstat after the issue has occurred.

You can create an alarm when an event is generated, As part of the alarm you can kick in a script. This script can be the one which goes to the filer and collects perfstat. In the below link there is a how to on the same.
Incase of client stats the following events are generated.
[root@ ~]# dfm eventtype list | grep -i clie
