tqdm-prometheus-exporter 0.1.10

Echo tqdm progress to a prometheus endpoint

Prometheus exporter for tqdm

Publish your pretty CLI stats for monitoring elsewhere

Usage

There are no security or authentication mechanisms provided, be careful exposing the host more widely

Initalise the proxy

proxy = TqdmPromProxy(http_host='[::1]', http_port=3000)
proxy.start()

Use the proxy

Replace tqdm initalisers with proxy.tqdm.

for item in proxy.tqdm(range(100), desc='My first bar')
    item.doathing()

with proxy.tqdm(range(100), desc='My second bar') as f:
    f.update(50)

# etc

If you require tqdm.write for sticky console output,

from tqdm import tqdm as tqdm_og
tqdm_og.write('Job done')

curl http://[::1]:3000/metrics

[!WARNING]
For windows users ensure you add this to your __main__ block, and before any initialisation of TqdmPrometheusProxy

from multiprocessing import freeze_support
freeze_support()
