Azure Windows VM Disk Usage report for All VM in a Azure Tenant

I was setting up monitoring for my Azure environment and I had an requirement to email the VM Disk usage of all windows VM's in a tenant to Support team on daily Basis and also sent notification in Slack. I used PowerShell to consolidate the data and Logic apps for the integration for Slack notification.


To breakdown the script for better understanding, I have used a credential from credential manager which had RBAC permissions to all subscriptions in the tenant and I used the function in  https://gallery.technet.microsoft.com/scriptcenter/Accessing-Windows-7210ae91 for my Azure and SFTP authentication using the credentials already in credential manager. I am using Invoke-AzVMRunCommand which basically runs a PowerShell script file on the remote server. The below PowerShell script will run C:\temp\GetDisk.ps1 on all the remote servers I am passing. 

GetDisk.ps1 runs the below PowerShell commandlet 

"Get-Volume|where {$_.FileSystemLabel -ne 'System Reserved' -and $_.FileSystem -eq 'NTFS'}|SELECT DriveLetter,Size,SizeRemaining|ConvertTo-Json"

Invoke-AzVMRunCommand Will return only as single string irrespective of output format so I have converted into json so I can easily convert to PSObject for processing in my main script.


The script will consolidate result in HTML format and Json format. Json format will be sent as Payload to Webhooks to Logic Apps were you can integrate with Slack or Teams alerts. HTML format will be styled with yellow rows for 10 to 15% free space and Red Rows for usage less than 10% free space as below.

Azure File Share Usage Report for all Subscription in your Tenant (Email and Web hooks notification)

 I was setting up monitoring for my Azure environment and I had an requirement to email the Fileshare usage of all fileshares in a tenant to Support team on daily Basis and also sent notification in Slack. I used PowerShell to consolidate the data and Logic apps for the integration for Slack notification.

To breakdown the script for better understanding, I have used a credential from credential manager which had RBAC permissions to all subscriptions in the tenant and I used the function in  https://gallery.technet.microsoft.com/scriptcenter/Accessing-Windows-7210ae91 for my Azure and SFTP authentication using the credentials already in credential manager. I am using Azure Management API's to get the information of the File storage as I found PowerShell Modules had restriction to Storage account opened only for particular subnet outside of the server I am running the script. I have used the method in  https://www.powershellgallery.com/packages/LSECosmos/0.2.1-alpha/Content/Get-AzAccessToken.ps1 for API Authentication.


The script will consolidate result in HTML format and Json format. Json format will be sent as Payload to Webhooks to Logic Apps were you can integrate with Slack or Teams alerts. HTML format will be styled with yellow rows for 80 to 90% and Red Rows for usage above 90% as below.
