Insights of Virtual Machine not showing all mount points
Hi, I have enabled Insights (in the Monitoring section of VM) on the Virtual Machine. But the `Max Logical Disk Used %` graph in Insights tab doesn't show all the mount points present in the VM. ...

Available memory is not available for virtual machines running Red Hat Linux (RHEL) 6. This metric is calculated from MemAvailable which was introduced in kernel version 3.14.
Metrics are only available for data disks on Linux virtual machines using XFS filesystem or EXT filesystem family (EXT2, EXT3, EXT4).

So do the mount points have an entry in the Time range you have selected, maybe increase the window?

Thanks for the reply.
No, increasing the time range doesn't help. It always shows only two mount points (the root and the temporary filesystem ` / ` and `/mnt` ). I have a 3rd mount point ( /home/test_mnt ) which doesn't show up in the query result.
Does the above statements mean VM insights do not show info about the attached disks ?
