1. What – if any – concerns does the Web Team have about the Editing Team potentially adjusting the rate at which the DesktopWebUIActions schema samples events at the wikis listed in ===Wikis impacted section above?

I'd be concerned about straining the infrastructure. The sampling rate is low as it is to intentionally avoid problems, however we do oversample for logged in users at 100% (using WMEDesktopWebUIActionsTrackingOversampleLoggedInUsers). I think you could similarly change the sampling rate on a per namespace basis, but please communicate with our analyst @jwang before and after any change.

Ideally any changes to the sampling rate would not impact article page views, as this is typically what we are monitoring during the desktop improvements project.

What – if any – concerns does the Web Team have about the DesktopWebUIActions schema being enabled on all wikis? As the Editing Team currently understands, the DesktopWebUIActions is not yet available/enabled on all wikis.

I think the only impact is that @jwang would need to adjust her queries to filter wikis, however I think she's doing that anyway. @jwang can you confirm?

Thanks for pinging me @Jdrobson.

We don't have ongoing experiment using DesktopWebUIActions schema now. The only impact is on the metric historical tracking. We can just note the change date in the graph or report if needed. Please keep us updated on the enable dates.

@ppelberg does the above answer your questions?
