Right now we can globally set when to go from detailed to hourly to daily for all tables but we can't set those value per table function.
For instance I want 90 day detail, 180 day hourly, and 365 day daily data for all the standard tables (traffic, response time, cpu, memory, etc)
But I would like ability to set lower retention settings for things like all the Wireless tables since they are growing huge under these settings and we don't typically care what a wireless user was doing traffic-wise 3 months ago.
I think it would be of great value to do a "detailed" section on the polling settings page to allow more granular control of not necessarily per table but definitely per technology.
