Previously, device name was used as service description for physical disks. Device names aren't persistent, which led to services starting to receive metrics of another device if device names get switched. This could happen after an update or a reboot.

Now, it's possible to configure WWN (World Wide Name) to be used as service description in the Disk IO discovery rule, in Physical disks configuration.

Old Physical disks configurations will continue to use device name as service description to preserve compatibility. For the new configurations using WWN will be the default.
