how to monitor intranet urls

Question

Is there a way to monitor private or intranet URLs hosted on VMs using a custom DNS server and behind a NVA ? Can this be achieved using Azure Application Insights standard web tests or Network Watcher connection monitor?

@$@chin Thank you for sharing additional details and apologies for the delayed response.

The scenario mentioned in the question would come under private testing. There are 2 ways to get this to work:

1. Public availability test enablement - In this case, a public DNS record is created for the intranet site and firewalls are enabled to allow testing from ApplicationInsights endpoints.
2. Using custom code and TrackAvailability() method of AppInsights API - In this method, the testing is done without making the Public DNS entry. Instead, a custom code is written which performs the test and uploads the result to ApplicationInsights resource. This code can be run as Azure Function or as a scheduled webjob or other mechanism. For an example code sample using this method, see TrackAvailability(): Basic Code Sample.
   The details of TrackAvailablity() method is available here - TelemetryClient.TrackAvailability Method

Hope this helps.
