This is a simple exporter for the Prometheus metrics using smartctl. The script smartprom.py also comes with smartprom.service so that you can run this script in the background on your Linux OS via systemctl. The script will use port 9902, you can change it by changing it directly in the script. This script exports all of the data available from the smartctl.

Docker image here: https://hub.docker.com/r/matusnovak/prometheus-smartctl

1. Install smartctl

yum install smartmontools -y

2. Clone project

git clone https://github.com/uncelvel/prometheus-smartctl
cd prometheus-smartctl

3. Copy the smartprom.service file into /etc/systemd/system folder.

cp smartprom.service /etc/systemd/system

4. Copy the smartprom.py file anywhere into your system.

cp smartprom.py /usr/sbin/
chmod +x /usr/sbin/smartprom.py

5. Install prometheus_client for the root user

yum install python3 -y 
sudo -H python3 -m pip install prometheus_client

6. Run

systemctl enable smartprom
systemctl start smartprom

7. Your metrics will now be available at

http://localhost:9902

No extra configuration needed, should work out of the box. The privileged: true is needed because then smartctl can't access drvies from the host.
