In the first part of our Azure Monitoring series, I showed you how to collect basic monitoring data from your Azure VMs. That was real time statistics but it was output everything on PowerShell console via Write-Host. It doesn’t make any sense because it’s not practical.

Now in this part, we will output all data into XML file, so you can use it on a website or on your CRM. You can also use .NET or PHP to parse XML data and put statistics onto website.

Following script is sample codes of VirtualMetric: Azure Module. You can check it from: http://www.virtualmetric.com

You will see xml files in the following directories. So you can make a website to parse that data.

This is demo page of VirtualMetric Azure Module:

http://virtualmetric.cloudapp.net/

You can download dashboard HTML files from here:

Download Azure Web Dashboard

That is a dashboard in realtime.

This is the first part of our Azure Monitoring script. It’s just a concept to show you how to monitor your Azure VM via PowerShell. Azure Powershell is not able to give performance data of virtual machines, so we will use remote PowerShell to connect Azure VMs.

My VMs are Windows Server 2012 R2, so Remote PowerShell is enabled by default on that servers. But if you are using earlier version of Windows, you should enable Remote PowerShell.

I simply used “Get-Credential” to get authenticated on Azure VMs but you can also store your password in a file as a plain text and use it to authenticate.

My Azure Subscriptions settings are in “Azure.Credentials.publishsettings” file. You can download it from Azure Website.

Following script is sample codes of VirtualMetric: Azure Module. You can check it from: http://www.virtualmetric.com
