launch jamf admin. this will mount the share. you can then see usage.

or check on the server / system that is providing the share

Can you please provide those steps 

@ashwina1995 Are you asking about the storage usage, or the amount of network traffic from your on-prem DP? Jamf Admin should show you the former, but there is no information in Jamf Pro on the latter.

I want to know those DP’s are still used for production or not. Does any end user machine utilise those DP or not. 

@ashwina1995 The only way I know of to determine that would be to look at policy logs which install something to see what DP they download the install package from.

If your Principal DP is a Cloud DP, and you don't have any Network Segments defined for your internal network that specify a Default Distribution Point which is one of your internal DPs, you could try just disabling your internal DPs.
