Configure the Azure Diagnostic Extension for Storing Linux Log Files

A colleague of mine was trying to figure out a cheap and simple way to store log files from their application and have the functionality to search through it. The first thing that came to mind was using an Azure® monitor to read the logs, but another option that most people forget is the Azure Linux Diagnostic Extension. This extension can collect metrics from the virtual machine (VM), read log events from the syslog, customize collected data metrics, collect specific log files that you can store in a storage table, and send metrics and log events to EventHub endpoints. The Azure portal lets the end-user configure all the preceding settings except collecting specific log files. Let me show you the steps required and a gotcha that sent me on a troubleshooting mission.

Using Azure proximity placement groups

I hardly ever see the Azure® proximity placement groups feature implemented for Infrastructure as a Service (IaaS) solutions. Do folks not know that this feature exists, or is it just one of the many components people forget when architecting? For those that do not know what a proximity placement group is, it is a logical grouping that tries to keep your virtual machines (VMs) physically close to each other to reduce network latency between those VMs.

Using Azure Private Endpoint with web apps

Azure® Private Endpoint provides private IP address access by using a network interface controller (NIC) attached to a virtual network subnet for an Azure web app, allowing access from an on-premise VPN or ExpressRoute. Implementing an endpoint effectively blocks the public inbound access. This technology is very similar to an internal App Service Environment (ASE) but much cheaper.
