iometrics

Network and Disk I/O Stats Monitor.

Usage

Monitor and log Network and Disks statistics in MegaBytes per second.

Pytorch-lightning integration

# TODO: add a pytorch-lightning integration example

Pure-Python implementation

Quick check:

python -c 'import iometrics; iometrics.usage()'

Full code:

import time
from iometrics import NetworkMetrics, DiskMetrics, DUAL_METRICS_HEADER
net  = NetworkMetrics()
disk = DiskMetrics()
for i in range(100):
    time.sleep(1)
    net.update_stats()
    disk.update_stats()
    print(DUAL_METRICS_HEADER) if i % 15 == 0 else None
    row = (
        f"| {net.mb_recv_ps.val:6.1f} | {net.mb_recv_ps.avg:6.1f} "
        f"| {net.mb_sent_ps.val:5.1f} | {net.mb_sent_ps.avg:5.1f} "
        f"| {int(disk.io_util.val):3d} | {int(disk.io_util.avg):3d} "
        f"| {disk.mb_read.val:6.1f} | {disk.mb_read.avg:6.1f} "
        f"| {disk.mb_writ.val:5.1f} | {disk.mb_writ.avg:5.1f} "
        f"| {int(disk.io_read.val):4d} | {int(disk.io_read.avg):4d} "
        f"| {int(disk.io_writ.val):3d} | {int(disk.io_writ.avg):3d} "
        f"|"
    )
    print(row)
