Explanation

You can create an Azure Function with TrackAvailability() that will run periodically according to the configuration given in TimerTrigger function with your own business logic. The results of this test will be sent to your Application Insights resource, where you will be able to query for and alert on the availability results data. This allows you to create customized tests similar to what you can do via Availability Monitoring in the portal. Customized tests will allow you to write more complex availability tests than is possible using the portal UI, monitor an app inside of your Azure VNET, change the endpoint address, or create an availability test even if this feature is not available in Standard tests are a single request test that is similar to the URL ping test but more advanced. In addition to validating whether an endpoint is responding and measuring the performance, Standard tests also includes SSL certificate validity, proactive lifetime check, HTTP request verb (for example GET,HEAD,POST, etc.), custom headers, and custom data associated with your URL Ping doesn't support checking SSL certificate. https://docs.microsoft.com/en-us/azure/azure-monitor/app/availability-azure-functions https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability
