Towards Sustainable Computing: Exploring Energy Consumption Efficiency of Alternative Configurations and Workloads in an Open Source Messaging System

This repository has been created to accompany the paper with the aforementioned title. It provides access to the testbed configuration of our system, along with the exported experimental data. As part of our work, we utilized the RabbitMQ project hua-geth, originally developed by another student at Harokopio University of Athens, Greece.

Setup Guide to measure metrics on a Ubuntu OS

This guide is a reference for the paper: "Green system design: Estimating the environmental footprint of computing systems"

In this README, you will find all the steps were done to setup the machine, to be able to measure energy and performance using Scaphandre.

Tech Stack (Hardware/Software)

The machine is an Intel PC architecture with Ubuntu OS. The tools needed:

• Kubernetes
• Docker
• Prometheus
• Grafana Dashboard

Setup Guide

Scaphandre Installation

$ git clone https://github.com/hubblo-org/scaphandre
$ cd scaphandre
$ helm install scaphandre helm/scaphandre

Prometheus Installation

$ helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
$ helm repo add kube-state-metrics https://kubernetes.github.io/kube-state-metrics
$ helm repo update

#Create port forwarding for Prometheus WebUI
$ kubectl port-forward deploy/prometheus-server 9090:9090

Docker Installation

$ sudo apt install docker.io
$ docker -version 
$ sudo systemctl enable docker 
$ sudo systemctl start docker

Docker UI Installation (to enable Kubernetes Engine)

# Add Docker's official GPG key:
$ sudo apt-get update
$ sudo apt-get install ca-certificates curl
$ sudo install -m 0755 -d /etc/apt/keyrings
$ sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
$ sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
$ echo 'deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$ (. /etc/os-release && echo '$VERSION_CODENAME') stable' | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

$ sudo apt-get update

$ wget https://desktop.docker.com/linux/main/amd64/145265/docker-desktop-4.29.0-amd64.deb

$ sudo apt-get install ./docker-desktop-4.29.0-amd64.deb

Prometheus Setup

$ helm upgrade --install prometheus prometheus-community/prometheus --set prometheus-node-exporter.hostRootFsMount.enabled=false --set prometheus-node-exporter.hostRootFsMount.mountPropagation='HostToContainer'
