Disk I/O Activity Monitor

Disk I/O Activity Monitor is a real-time block storage telemetry viewer and
dual-line IOPS/throughput oscilloscope for Linux workstations and servers.
An independent Linux alternative to desktop disk activity monitors such as
DiskMon and command-line iostat, it polls kernel /proc/diskstats and
/sys/class/block/*/stat counters without requiring raw block-device access.

Key Features:
- Live IOPS & Throughput Telemetry: Polls /proc/diskstats and /sys/class/block
across configurable intervals (250 ms to 5 s) to compute real-time Read/Write
IOPS, Read/Write MB/s, average request size (KB), and device utilization %.
- Queue Depth & Latency Metrics: Tracks active in_flight queue depth, I/O service
time (ms), and weighted queue time (ms) for NVMe, SATA/SCSI, virtio, and mapper
block devices alongside hardware model, capacity, and scheduler metadata.
- Dual-Line Oscilloscope Charts: Renders live Read/Write IOPS and Read/Write MB/s
oscilloscope waveforms for all active drives or any selected block device.
- Baseline Session Delta & Exports: Resets session counters on demand to measure
workload I/O totals and exports telemetry snapshots and history to CSV and JSON.
