Live reports
Live reports are flat-list reports that update data in real time with hourly granularity. Use Live reports to see the most current data on your site and to analyze hourly trends.
Live reports are always run on a full data set at report viewing time. Therefore, sampling, data set, and distribution options available for other reports are not available for Live reports. In addition, calculated metrics, segmentation, targeting, annotation, relational zoom, and distribution options are not available for Live reports.
Live report data is retained for a minimum of eight days, which allows you to compare data from the current day with the same day of week from the previous week.
