Hello, I'm getting an error when attempting to start the infiniband exporter service:

Started Infiniband_exporter. Aug 11 14:20:42 \ python3[374627]: Traceback (most recent call last): Aug 11 14:20:42 \ python3[374627]: File "/usr/bin/infiniband_exporter.py", line 12, in Aug 11 14:20:42 \ python3[374627]: from prometheus_client.core import CounterMetricFamily, GaugeMetricFamily Aug 11 14:20:42 \ python3[374627]: ModuleNotFoundError: No module named 'prometheus_client' Aug 11 14:20:42 \ systemd[1]: infiniband_exporter.service: main process exited, code=exited, status=1/FAILURE Aug 11 14:20:42 \ systemd[1]: Unit infiniband_exporter.service entered failed state. Aug 11 14:20:42 \ systemd[1]: infiniband_exporter.service failed.

Is there a dependency that I am missing - CounterMetricFamily, GaugeMetricFamily ? If so, where do I get it?

i'm using v 0.0.4

Thanks

Hi, This module currently need to be installed manually with pip3 install prometheus-client.

python2 support for this program was removed in the latest release, previously this was using python2-prometheus_client from epel to provide this module and there are no python3-prometheus_client available on Centos 7.

A small warning was placed in the README.md in this commit https://github.com/guilbaults/infiniband-exporter/commit/20dcf98d44552a58aed8105bab2a70a1610fdd7d

The upstream module: https://pypi.org/project/prometheus-client/

Hi,

you can also use Miniconda for resolving dependencies in Python.
It is a great tool. I just use the installer and then manage the dependencies.
With that you can also get different Python versions and environments running easily.

I have written some notes about that here.

The prometheus_client is also available there: 

$ conda search prometheus
prometheus. Search: *prometheus*
