Availability Tests with Azure Application Insights

Azure Application Insights provide a great way to log the application events and query them without much of a hazel. Availability test is an option that lets you either ping a server and test or run Multi-step tests.

These can be run in intervals of 5, 10 or 15 minutes and also can be set to ping them within different regions.


Apart from those settings, it also allows setting timeouts. If a time out happens, then it can be configured to retry up to 3 times with 20 second intervals. An item will be considered as a failure only if it fails the retry attempts.
Full documentation on App availability can be found here: https://docs.microsoft.com/en-gb/azure/azure-monitor/app/monitor-web-app-availability

This is totally free for unlimited attempts. But if you try the multi-step web tests, it will cost 10 USD per test per month, running unlimited instances. So, why do not you try it away?

Administering Azure Functions in Portal

Azure functions can be easily managed within the Azure Portal. Though there are certain restrictions, it allows managing the functions and executing them within the portal itself.


Once you navigate inside the function, you can see all available functions within that function app. All the functions I have in the above screen are Http Triggers.

Setting Up APIM Policies - UI Setup

In my previous articles I introduced Azure API Management Service and how to use it to host an Azure function. In this article I will explain the policies that can be applied. Once you open up an API, it shows all the placeholders for creating policies as below.

In the Inbound and Outbound processing sections you have the option to Add Policy via an interface. But that will be directed to code view if you add some complex logics. Then it will only enable the code view as below.

Products basics for API Management

Products are the means for exposing APIs for the developers. In order to add a product, go to Products tab on the API menu.
You can see already two products there. They basically show up the possibility of limiting the quotas to be used by the developers. Unlimited one does not has any restrictions applied, but the Starter has a rate limit and a quota limit policies applied under its policies.

Azure provides comprehensive set of options for managing APIs. API Management Service is one of such that let you control the access granted to outside. Getting started with API Management Service is easy. The new API Management Service wizard will open up like this.


Once all the required fields are filled and validated, you can access the API Management Service (APIM) through the portal. In this article I will explain an overview of what are the sections available and what each section does as I am intending to write detailed specifics in some sections in coming articles.
