[Bug]: Disk throughput not being shown on NTFS mounts

[iassis]

Component

Hub

Description

Beszel Hub shows the disk space usage, however, it can't really show any disk throughput for NTFS mounted drives. The problem manifests on both USB as well as HBA attached drives in a Windows VM I have, literally all drives (10x+ HDD's + 1x NVMe) are suffering from this behavior in Beszel Hub.

Example:

Expected Behavior

The disk throughput utilization should be shown in the graph as it does properly for root partitions/disks:

Steps to Reproduce

This is my build:

• Proxmox host
• Windows 11 IoT LTSC VM [v10.0.26100, Build 26100]
• IBM M1210 HBA (flashed with 9300-4i IT mode firmware) passed through from PVE to VM
• USB to NVMe adapter with Jmicron JMS583 chip passed through from PVE to VM
• HDD's: Seagate Barracuda 8TB + Seagate Exos 26TB
• NVMe: WD Black SN7100 4TB

Beszel configuration:

• ZimaOS v1.5.2 host
• Docker v0.16.1 image for both hub and agent
