Mobile App autoinstrumentation: action "Redisplay UIWindowScene" with outrageous response times

[antonio_villarr]

Hi,

One customer is starting to use the oneagent sdk for ios on a mobile app. They are reporting that lots of user actions with the name "Redisplay UIWindowScene" are shown, with response times above 1 minutes (sometimes 3 or 5 minutes), however in the tests customer has done the response times of the actions in the app are normal (a few seconds, and never above 1 minute).

Questions:

1.- do you know what represents this action? Sometimes it appears in sequence in a session

2.- Why the response times are so high?

Any help is appreciated.

Kind regards,

Antonio V.

Did you just start seeing these high numbers? I'm wondering if Dynatrace is grouping other actions into this one thus adding to the large number. It might be wise to open a support if the data is showing up incorrect per your tests

UIWindowScenee appeared with iOS 13. We are currently investigating under which circumstances such long times can be caused.
Only workaround we can offer at this time is to exclude UIWindowScene from instrumentation:

<key>DTXExcludedLifecycleClasses</key>
<array>
    <string>UIWindowScene</string>
</array>

there was a bug with the exclusion that was fixed in 8.203 - additionally the issue with the long timings was fixed in 8.209 release of the iOS Agent

Thank you for the response. The last data shows times around 7s, which is still high for customer to consider. I think I will try to exclude this action.
