  • CPU: utilization, frequency, temperature (@mccooeyc11)
  • RAM: utilization, total memory installed (@l3331l4)
  • Network: traffic in, traffic out (@cindyariyo)
• Added unit tests for each of the above, fully integrated in the CI pipeline.

Configurations

• Configure Prometheus to scrape metrics from our exporter, alongside Node Exporter.
