I don't see the ability to do any type of calculation in user session queries. I can get at the total number of actions and the total number of errors, but not divide those out for the user to display a percentage. Is there a way to do something like that with custom charts or user session queries that I'm not finding? I'd be interested in doing this for things other than errors as well, like what % of user actions were satisfyied vs frustrated.
No you cannot calculate percentage values here. At least not yet. You can post RFE for such things. You can make such calculations only when you extraxt USQL data via API and do it by some external script or tool. You can POST an RFE here but what you need my need nested queries or combining data from multiple ones. It may be complicated but I agree that would be nice to have such things 🙂
