Question:
How to generate a report on number of hits to each services daily basis?

Answer:
We have Dashboard in NetScaler GUI however that will only display current statistics for NetScaler.
We can use NetScaler Insight Center.
It is a virtual machine designed to monitor NetScaler connection activity and it also allows us to generate PDF reports.

# NetScaler 11.1 in Reporting now has option to export statistics for services hits and export it to csv file.
