Enhancements to VMware Tools 12 for Container Application Discovery in vSphere 

by // 2 Comments

VMware Tools 12 was just released and it adds a number of new features including support for Windows 11 and Windows Server 2022, Salt Stack Minion deployment and the use of OpenSSL 3.0 library to just name a few.

One additional feature that is quite interesting is the enhancement to the Application Discovery feature that was shipped with VMware Tools 11 which provides organizations with additional visibility of the running processes within a VM.

With VMware Tools 12, we now have a more granular method for discovering container-based processes (Docker or Containerd) running within a Linux VM, which is pretty cool if you ask me!


Similiar to the Application Discovery feature, a new VM guestinfo variable has been introduced called guestinfo.vmtools.containerinfo that will be populated with the list of running containers. By default, the polling interval is every 6 hours with a default of listing the first 100 containers, these and other settings can be adjusted which you can find in the official VMware documentation.

Simliar to the Application Discovery feature, I have also updated my PowerCLI function Get-VMApplicationInfo.ps1 to include this additional functionality for users that would like to extract this information and I have created a new function called Get-VMContainerInfo, which you see how it functions in the screenshot above. In addition to console output, you can also save the information in both CSV and JSON format.

PowerShell community module for Application Transformer for VMware Tanzu

by // Leave a Comment

In the previous blog post, we explored the Application Transformer for VMware Tanzu REST API and how it can be used for automation and more advanced workflows. To simplify the consumption of the App Transformer REST API and how I started to explore and learn about the APIs, I created a PowerShell module for App Transformer that implements a number of the App Transformer REST API that can easily be consumed using the following functions:

  • Connect-AppTransformer
  • Get-AppTransformerApplication
  • Get-AppTransformerComponent
  • Get-AppTransformerComponentSignature
  • Get-AppTransformerCredential
  • Get-AppTransformerNetworkInsight
  • Get-AppTransformerVCenter
  • Get-AppTransformerVM
  • New-AppTransformerCredential
  • New-AppTransformerCredentialAssociation
  • New-AppTransformerNetworkInsightCloud
  • New-AppTransformerVCenter
  • Remove-AppTransformerCredential
  • Start-AppTransformerIntrospection


🥳 To help celebrate the official GA of Application Transformer for VMware Tanzu today, I have just published my PowerShell Community Module for App Transformer into the PowerShell Gallery!

Getting Started with the Application Transformer for VMware Tanzu REST API

by // Leave a Comment

An extremely powerful capability of Application Transformer for VMware Tanzu is not just getting application data and custom information into App Transformer, but that you can also easily extract that information and use that for a number of other scenarios including but not limited to internal true up of your deployed applications versus what is currently in your Change Management Database (CMDB), inventory analysis across your application vendor and/or versions for auditing, licensing and compliance to identifying vulnerable software versions. The use cases for App Transformer certainly span beyond just App Modernization and can truly be endless!


The App Transformer UI is just one way in which users can interact with the solution but for more advanced workflows or automation purposes, users can also leverage the App Transformer REST API. In this blog post, we take a look at how to get started with the App Transformer REST API.
