Report scheduling

Hi, am currently evaluating this product and need the following.

1. I would like to schedule a report (current as well as historic) with a particular destination, protocol and all the conversations for the selected period. I am trying my best but not been successful. I just need one consolidated report of the above. Pls advise step by step procedure.

2. I was able to manually drill down to the info I have asked above. The report shows OUT data in MB, but IN is ZERO for all the conversations to that particular web server. Pls clarify.

3. In the device property, how do I arrive at Uplink and Downlink speeds. Are these the WAN link speeds? If there are multiple links thru the same firewall, do i have to enter a cumulative figure?

4. Any housekeeping procedures or settings to trim database sizes?

Highly appreciate,
Thanks,
Arun.
