@sonal khatri , thank you for posting this question here. I understand that you are trying to see the failures in the application from "Failures" option of the ApplicationInsights.
It seems that the screenshot shared are for one of the top 3 response code only and it appears that you have selected "Error code 409" to be viewed. Refer to the screenshot below:
Note that the failures could also be related to Exceptions (2), dependencies(3). All this data is pulled from the ApplicationInsights logs and if required, you could also check the suggested queries as highlighted below.
Hope this helps. Please let us know if you have any questions.
