- From 40 to 260 events logged per second in a month: what's going on?
Eep, thanks for raising the alarm. MediaViewer is 170 events / sec, MultimediaViewerDuration is 38 / sec.
+CC Multimedia.
We log one duration event and a bunch of user action events (clicked on button X etc) per lightbox view. Is that a problem? On what front? (Logging infrastructure performance? Privacy? Client-side performance?) Expectations on how to use EventLogging should be clearly documented somewhere.
I can add sampling to these events, if this is a serious problem; although logging several events per page view is a pretty standard thing for analytics tools AFAIK. (Also if there are performance issues, maybe EventLogging should provide a batch logging option?)
