What is the Concurrent Visits report in Piwik PRO Analytics about?
This report tells you exactly how many active visits your website records over a short period of time (e.g. every 10 minutes). This information is intended to help you schedule the release of new content at the right time which maximizes the impact of your campaigns or activities.
In the lower-left corner of the report, you can choose between three standard time spans of ten, fifteen and twenty minutes. Additional spans can be added in the config file if needed.
