fsmon: A Real-Time Btrfs I/O Monitor

fsmon monitors the I/O activity of Btrfs filesystems in real time, displaying bandwidth and IOPS statistics for detected filesystems and their devices.

It combines I/O statistics from all member devices of each Btrfs filesystem, providing a unified view of the filesystem's overall activity.

Features

• Real-time monitoring of read/write bandwidth and IOPS.
• Visual charts for I/O statistics.
• Dynamic terminal size handling.
• Lightweight and efficient, leveraging sysfs for minimal overhead.

Requirements

• Python 3.6 or higher.
• Btrfs filesystems mounted on the system.
• Sufficient permissions to access /sys/fs/btrfs and related devices in /sys/block.
