Is there a way to find out what pi points are being accessed during a period of time?
I want to know what points our PI users are actually using and find 'redundant' points to remove.
Currently, there doesn't seem to be a way to find out what points are being accessed during a period of time. There used to be a tool called AAG for versions 3.3.xx to 3.4.390.xx of the PI Data Archive that allowed determining which PI tags had been recently accessed by certain clients or users. However, that tool is no longer available and an enhancement request exists to create an improved tool to serve the same purpose: Known Issue 120488 - Improved tools for tracking PI Server utilization.
I would also suggest submitting this idea to our feedback website Customer Feedback for OSIsoft & the PI System where ideas can be more easily tracked and up-voted.
I've submitted the idea as
Provide "Point Last Accessed" information to determine clients' use of PI Points
