Network and Disk I/O Stats Monitor

Project description

iometrics

Python

Network and Disk I/O Stats Monitor.

Usage

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

Pytorch-lightning integration

from pytorch_lightning import Trainer
from iometrics.pytorch_lightning.callbacks import NetworkAndDiskStatsMonitor

net_disk_stats = NetworkAndDiskStatsMonitor()

trainer = Trainer(callbacks=[net_disk_stats])

Metrics generated:

  • network/recv_MB_per_sec – Received MegaBytes per second (MB/s) on all relevant network interfaces as a SUM.
  • network/sent_MB_per_sec – Sent MegaBytes per second (MB/s) on all relevant network interfaces as a SUM.
  • disk/util% – Disk utilization percentage as the average of all disk devices.
  • disk/read_MB_per_sec – Disks read MB/s as the sum of all disk devices.
  • disk/writ_MB_per_sec – Disks written MB/s as the sum of all disk devices.
  • disk/io_read_count_per_sec – Disks read I/O operations per second as the sum of all disk devices.
  • disk/io_writ_count_per_sec – Disks written I/O operations per second as the sum of all disk devices.

Pure-Python implementation (zero dependencies)

Quick check

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