Using Application Insights in order to keep track of your Azure Functions

The last two posts had me writing about how logging can be implemented in your Azure Functions and how you can reuse class libraries using a different logging library, like log4net. You probably already have some logging- and monitoring system in place, but if you’re starting to use Azure Functions (or any other Azure service for that matter), the best tooling to use is Application Insights, in my opinion. You don’t even have to use Azure services in order to use Application Insights. Read more →

Using log4net in your Azure Functions

As I mentioned in my earlier post, there are 2 options available to you out of the box for logging. You can either use the TraceWriter or the ILogger. While this is fine when you are doing some small projects or Functions, it can become a problem if you want your Azure Functions to reuse earlier developed logic or modules used in different projects, a Web API for example. In these shared class libraries you are probably leveraging the power of a ‘full-blown’ logging library. Read more →

First steps into logging of your Azure Functions

Creating a solution with multiple small services is great of course. It provides you with a lot of flexibility and scalability. There are however a couple of things you have to think about when designing and developing a solution with multiple services. One of the things you need to figure out is how to implement proper logging. For an actual production system you need to have this in place in order to monitor and debug the overall solution.

Setting up an Azure Active Directory application to retrieve Let’s Encrypt certificates

So you might remember me posting about using the Let’s Encrypt site extension for Azure App Services, called Azure Let’s Encrypt, created by SJKP. This has quite well for over a year now and even works for Function Apps. However, last month I got notified my SSL certificate was expired on one of my sites. Strange, as an automated job should just handle this for me. I thought the job probably didn’t execute because of some glitch in the matrix. Read more →

Move Up with Azure

In a couple of weeks, on the 22nd of February, I’ll be talking at a free event organized by 4DotNet and SnelStart called Move Up with Azure. I’m not the only one who will be speaking over there, there’s also a great session by Henry Been (SnelStart) and an awesome talk from Christos Matskas (Microsoft). I myself will be talking on how to create a serverless solution using Azure Functions. This of course is a very broad subject and I’d like to know what you think I should focus on or what you would like to see covered in this session? Read more →
