Is there some way how to monitor free disk space from the Azure Portal?
I know that there are all kinds of diagnostics for I/O, memory, network, CPU, .NET, SQL, ASP.NET, IIS, etc.
But is there some way to see how much free space there's on a disk attached to the VM?
All I found was this third-party solution:

But there should be some way how to see a basic metric like disk space without needing third-party SW, right?

Update 2019
This is possible today. To monitor free disk space per drive with Azure Monitor do the following:
- Enable Guest Operating System OS Metrics for the VM.
- In the Azure Portal select the Virtual Machine.
- Click Diagnostics Settings (under Monitoring).
- Click the Performance counters tab.
- Click the Custom button.
- In the textbox add the custom metric for the drive you would like. e.g.
\LogicalDisk(C:)\% Free Space. - Click Add and set the Unit to
Percent.

For now, it is not possible on Azure Portal.
But you could do it by using Azure OMS. There is a example how to use Azure OMS to monitor free disk.

This is not possible today through Azure Portal or Azure Monitor. Free disk space is a guest OS performance counter. If this is a Windows VM, you can use the Windows Azure Diagnostics (WAD) agent to collect performance counters to either Azure Storage table and/or EventHub and setup custom tool to monitor this data. If this is a Linux VM, there is also the equivalent Linux Diagnostic Extension.
Here are some relevant links on WAD -
