I have an already published application running several MS SQL Server 2000 Reporting Services report.
I need a way to find from either the reporting services log or the application server (IIS) logs or windows log
to know the frequency of each report being used.

Based on this info, the business needs to know which reports are being used and to what extend?
How can I acheive this?

I have already got the IIS logs and it did not give the required info.
I have looked into the Reporting Services logs but it does not provide the info either.

Any help is appreciated
