How to log the Event URL field in Kentico for 404 pages in Azure Application Inisghts?

Question

I would like to log the "Event URL" field in Kentico Portal logs to Azure Application Insights for 404 requests. Since I changed my custom page for 404 errors in Kentico Portal I only get "PortalTemplate.apsx" for the url field in the requests table in AppInsights.

We already have this as a recommendation on the GitHub - use RawUrl instead of Request.Url .

As explained here RawUrl better suites cases when the request was redirected to the custom error page: Request.RawUrl vs. Request.Url

Please upvote the issue on GitHub. As a workaround now you can replace OperationNameTelemetryInitializer in ApplicaitonInsights.config to your own implementation of it that uses RawUrl instead of the Url .
