How can I change date interval in ASA to pull reports?

[1SIKV35]

How come I can't change the date interval on my ASA?

I'm trying to pull Trunk and Call Traffic info but it's not allowing me to change the date. It's stuck on one day time period. I can drop down the calendar, but it won't let me select any other day.

Thanks.

You need to go to the "fault and performance" tab and setup the data polling schedule. ASA needs to poll the system daily. You can't change the date because you currently have no data for those other dates. After you setup the polling, you will have data from that polling date forward.
