Can you please provide guidance for an SQL query or point to existing piwik code which can be used to display (in number and/or in graph) ad hoc stats?
I am mainly interested on unique visitors and pageviews per minute and per second over selected short time periods.
An ad hoc stats page like the above would be a great addition to Piwik! (Admins will be using it at their own discretion to avoid overloading their servers.) Yet, even if you can provide directions for a suitable SQL query, that would do the job, for the time being.
Thanks in advance,
