iometrics
Monitor and log Network and Disks statistics in MegaBytes per second.
Install
pip install iometrics
Usage
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 MB/s on all relevant network interfaces as a SUM.
- network/sent_MB_per_sec – Sent 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.
