Panorama: Long-term trend analysis of Oracle database workload
Why Oracle DB allows retrospective evaluation of workload of active sessions by Active Session History (ASH) if you have Enterprise Edition and Diagnostics Pack. The default retention time for ASH is 7 days back from now, usual settings for production are around 30 days. But sometimes you need to analyze the evolution of database load over longer periods like over many years (e.g. as base for hardware planning and capital budgeting).

What Panorama-Sampler allows you to extract some information from ASH and store it compressed as summary other periods between one hour and one day.
