We have a project that is hosted via Azure Function app, and sits behind APIM. We noticed that the number of requests in APIM is not equal to the number of requests in the Function App. Also checking the requests on APIM, they are all success == true and resultcode ==200. But those requests were not able to trigger the function app. We verified that our function app was not triggered as no updates were found on the other application being called by the function app. We also noticed that this only occurs during high volumes of request coming in. Are there any settings or configurations, we need to check with this?
