Hi Team,

we can see 100% Disk utilization (PFA Snapshot) in the configured dashboard but on the host level, we are unable to find the listed Disk. An anyone help me to understand why we are unable to see it?

Hi @Vikas_g1997 

Did you choose the right measure (Disk used %) to present the data and did I set a filter for a specific host?

See my example below:

Hi @radek_jasinski ,

We have used the below metric.

MerticMertic

Use this metric: Disk used % (Auto)
The data should then match:)

Hi @radek_jasinski ,

Hi @Vikas_g1997,

in the second screenshot, I can see it's an unknown disk, can you check if show all NFS disks option in the host's settings is enabled or not, if not enabled then try to enable it and let us check again.

Hi @Vikas_g1997, did you have a chance to try what Mohamed suggested? Did it help?
