Description:

iometrics 0.0.8

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.

Run in a Docker container
Containers don't have access to the host's network statistics, therefore this workaround is needed.
# on the host machine (not inside the container)
iometrics replicate proc &

after you run above script in the host you should mount the /host/proc/net/dev to the container. for example:
docker run -it -v "/tmp/proc_net_dev:/host/proc/net/dev:ro" <YOURIMAGE>
