Find disks attached but not mounted

Is there a metrics that will provide me information about disk which is attached to an cloud instance but not mounted, basically its not in use and costing us money?
I saw under node-exporter few disk metrics which are set to 0 but now sure if that is what i want. The metrics in question are:
node_disk_reads_merged_total
node_disk_write_time_seconds_total
node_disk_writes_completed_total
node_disk_writes_merged_total
node_disk_written_bytes_total

Thank you!

Hi @marathiboy,

Thanks for opening this post.

You can use some other community based exported scripts which might have what you looking for while directly Prometheus Node Exporter seems to not have all such features.

I found the following might be interesting for you to try out (use one of them or combine together):

1- Prometheus Disk Usage Exporter

2- Prometheus Disk Exporter

3- Prometheus Node-Exporter (all mounting points)

I hope this helps. :slight_smile:
