I have two resources, a VM and a VMSS Instance. I'd like to check how much disk space I've used. Please help.

    Hi @Vincent Li ,
    memory is not your disk, it's your RAM.

    I'm also looking for a possibility to see the VM's disk usage. I'm wondering why such an important information is not shown in Metrics.

    Hi VincentLi,
    From my experience the best way to monitor all resources is to enable logging to Azure Monitor.
    Once you’ve enabled logging all the health stats you can ever want will be available via kql queries.
    Good luck!

    In VM Diagnostics settings, if you enable guest monitoring, you can find the disk space consumption details easilty.
