What is the difference between users "impacted" and "affected" by an error?


Hi all,

47 User sessions impacted, but "no user sessions were affected by this error"?

Hi @yair_mashmor,

The number of impacted users in the problem card is the number of "Observed Users" i.e. refers to the potentially impacted users. These are the users that have been observed to be using the app in that timeframe.

For example, If you experience a backend issue you probably might be interested in the number of users that were observed accessing those specific traces. It's not that we simply show 'ALL' users. It's specific users for the app that is affected by the backend service issue, hitting user actions being on the same pure path at the time we detected that problem.

However, when you try to drill it down to the affected users, it shows a different number/no users as the source is different. Davis is using a different data storage to calculate the potentially impacted users than the USQL. In this case (based on your screenshot), looks like there were no users who faced any HTTP error or were affected by this problem in using the application.

Hope this helps.

Kind regards,
