⚡ Azure Visualizer, aka 'AzViz'

PowerShell Gallery PowerShell Gallery GitHub issues CI Documentation Status License

Azure Visualizer aka 'AzViz' - PowerShell module to automatically generate Azure resource topology diagrams by just typing a PowerShell cmdlet and passing the name of one or more Azure Resource Group(s).

Cloud admins are not anymore doomed to manually document a cloud environment! The pain of inheriting an undocumented cloud landscape to support is gone 😎😉 so please share this project with your colleagues and friends.

Buy Me A Coffee

It is capable of:

  • Finding Resources in a Azure Resource Group and identifying their dependencies.
  • Plot nodes and edges to represent Azure Resources and their dependencies on a graph.
  • Insert appropriate Azure Icons on basis of resource category/sub-category.
  • Label each resource with information like Name, Category, Type etc.
  • Generate visualization in formats like: .png and .svg
  • Output image can be in 'light', 'dark' or 'neon' theme.
  • Can target more than one resource group at once.
  • Change direction in which resource groups are plotted, i.e, left-to-right or top-to-bottom.

Thanks and shoutouts

Special thanks & shoutout to Kevin Marquette and his PSGraph module which seeded the idea for programmatical approach to Azure Visualization while I was working with Kevin's module. And without which 'AzViz' module won't be possible! ♥👍

Change Log

v1.2.1

  • Fixed casing for loadbalancer.png in AzViz/src/private/Images.ps1 to match the filename for AzViz/icons/LoadBalancers.png as AzViz could not find the icon when run from pwsh on a Linux VM. pull-request by @madsaune

  • Handled condition to skip resources out of resource group, this should fix issue#37 and issue#39
  • Handled period in resource group name, this should fix issue#41
  • If there are no edges between the nodes, then graph legends are not plotted, this should fix issue#38
  • Empty resource groups skips, resource visualization for all later targets, this should fix issue#50. Thanks @madsaune finding the bug and creating the issue.
  • Add Vnet-only resource groups to graph visualization. Special thanks to @madsaune for the pull-request
