Title
"VMW Virtual Machine Logical Drive Estimated Fill Time" rule fires false alarms for non-existent logical drives -
Description
"VMW Virtual Machine Logical Drive Estimated Fill Time" rule fires false alarms for non-existent logical drives. The /tmp and /var/tmp file systems do not exist on the server.
But for some reason, Foglight picks them up and alerts about the estimated fill time.

Cause
A deeper investigation suggested that the issue is probably with the combination of CentOS 7.4 and open-vm-tools-10.1.5 and not specifically with the Foglight as Foglight just displays what is collected via the API.** CentOS 7.4 VM (open-vm-tools-10.1.5) **PS C:\> $vmguest = get-vm FQDN | get-vmguest; foreach ($disk in $vmguest.Disks) { $disk | select Path }Path----//boot/var/log/tmp/var/tmpBut the same query returns accurate and desired results on CentOS 7.5 and open-vm-tools-10.1.10.** CentOS 7.5 VM (open-vm-tools-10.1.10) **PS C:\> $vmguest = get-vm FQDN | get-vmguest; foreach ($disk in $vmguest.Disks) { $disk | select Path }Path----//var/log/boot -
Resolution
Upgrading to CentOS to 7.5 and open-vm-tools to 10.1.10 helped resolved the issue.
