Numbers for diagnostics metrics of VM on portal.azure.com dashboard seem incorrect


On Azure, I have a Linux VM. I enable Diagnostics settings on this VM 3 days ago.

The virtual machine has a 30 GB disk of which 16 are used. But Azure Monitor chart for "Filesystem free space" showing that I have 149 GB free space and "Filesystem used space" 24.5 GB.

Why is that? Is it correct? Can I debug this?


Solution

  • In this case this is the expected behaviour due to the temporary disk attached to azure vm
