If you want to chart out something like disk space for Windows machines, the PRTG Grafana plugin pulls the disk serial, as separate sensors each.
To query all of your Windows disk space sensors (from a Group) at once, you can set the following (head to the Query window):
Field | Value to Use |
---|---|
Query Mode | Metrics |
Group | Windows (for example) |
Host | * |
Sensor | /Disk Free: C\:\\ Label\: Serial Number */ |
Channel | Free Space |
Note that special characters have to be escaped, else the regex won't parse correctly.
