How does real-time analytics differ from a historical report?

The time window and the purpose. A historical report is built on daily, weekly and monthly ranges so trends can be analysed; a real-time view holds only the last few minutes so the effect of a publication, a campaign or an incident is visible immediately.

Why does the live figure not match the next day's report?

The final report is computed on completed data: late events are added, de-duplication runs across the whole range, and filters are applied. A small gap is expected, and the historical report is the number of record.

Real-time analytics is the display of site events within seconds of them happening, over a short rolling window instead of a daily or weekly range.

An event travels from the browser to the server and is counted directly against a window of the last few minutes, with no batch processing step in between, while the view keeps itself fresh through a persistent connection or polling. That short path has a cost: fewer dimensions are available, the window is small, and metrics that need de-duplication across a whole period do not carry an exact meaning in this view. The common mistake is to compare a live figure with a historical report and read the gap as a bug, when in fact the two are different windows at different processing stages. Real-time analytics is a monitoring and reaction tool, not the basis for reporting or long-term decisions.
