Application Insights (AI) is the application performance management (APM) and logging platform for Microsoft Azure. They provide a client instrumentation library for several popular platforms/languages– but there isn’t any official module for PowerShell. In this post I share some new functions that demonstrate how to log telemetry data to AI from PowerShell.Continue reading
Deploying Azure Resource Manager (ARM) templates with the Azure PowerShell command New-AzureRmResourceGroupDeployment can fail for a variety of reasons. One of the more confusing situations can occur when handling template validation errors (Code=InvalidTemplateDeployment). This is because sometimes additional context is missing from the Exception and you have to lookup more information into order to troubleshoot the issue. In this post we will take a closer look at this particular error and how to resolve it.Continue reading
I recently completed work on a my first compiled binary PowerShell module– these are modules built with C#/.Net code instead of PowerShell code. A few module development basics like project setup, handling help files, and writing unit tests did take some work to figure out. In this article I provide some tips for how to handle these common scenarios to help you get started on new projects.Continue reading

Since this problem isn’t covered in the official documentation I figured it deserved a quick write-up.Continue reading
A couple years ago I wrote a PowerShell module starter kit (here). The goal was to provide an example for organizing a module using best practices and provide a live repository you could clone and play around with.
I’ve taken that starter kit module and updated it for 2019. Incorporating some new best practices and new usage patterns that I find helpful. Head over to the GitHub link to check it out!
The ‘copy’ property is an Azure ARM template feature that allows you to iterate (for each) loop over a resource to create multiple copies of it. You can combine it with an ‘array of objects’ custom parameter to easily duplicate resources with your supplied values. However there are a couple of snags you might run into so I figured it’s worth a write up with an example.Continue reading

You immediately hit this all too common error: “New-AzureRmResourceGroupDeployment : A parameter cannot be found that matches parameter name ‘<myParameter>’“.Continue reading
