Prometheus Server Configuration on AWS EC2 Machine

By -

Prometheus Server Setup:

Step 1: Update the yum package repositories.

sudo yum update -y

Step 2: Create a Prometheus user, and required directories, and make the Prometheus user as the owner of those directories.

sudo useradd --no-create-home --shell /bin/false prometheus

sudo mkdir /etc/prometheus

sudo mkdir /var/lib/prometheus

sudo chown prometheus:prometheus /etc/prometheus

sudo chown prometheus:prometheus /var/lib/prometheus

Step 3: Go to the official Prometheus downloads page (https://prometheus.io/)and get the download link for the Linux binary.

https://github.com/prometheus/prometheus/releases/download/v2.36.1/prometheus-2.36.1.linux-amd64.tar.gz

Step 4: Download the source using wget, unzip the package then rename the extracted folder to prometheus-files.

wget https://github.com/prometheus/prometheus/releases/download/v2.36.1/prometheus-2.36.1.linux-amd64.tar.gz

tar -xvf tar_pkg_name

mv prometheus-2.17.3.linux-amd64 prometheus-files

Step 5: Copy Prometheus and promtool binary from prometheus-files folder to /usr/local/bin and change the ownership to prometheus user.

sudo cp prometheus-files/prometheus /usr/local/bin/

sudo cp prometheus-files/promtool /usr/local/bin/

sudo chown prometheus:prometheus /usr/local/bin/prometheus

sudo chown prometheus:prometheus /usr/local/bin/promtool

Step 6: Move the consoles and console_libraries directories from prometheus-files to /etc/prometheus folder and change the ownership to Prometheus user.

sudo cp -r prometheus-files/consoles /etc/prometheus

sudo cp -r prometheus-files/console_libraries /etc/prometheus

sudo chown -R prometheus:prometheus /etc/prometheus/consoles

sudo chown -R prometheus:prometheus /etc/prometheus/console_libraries

Setup Prometheus Configuration:

All the Prometheus configurations should be present in /etc/prometheus/prometheus.yml file.

Step 1: Create the prometheus.yml file.

sudo vi /etc/prometheus/prometheus.yml

Step 2: Copy the following contents to the prometheus.yml file.

global:

  scrape_interval: 10s

scrape_configs:

  - job_name: 'prometheus'

    scrape_interval: 10s

    static_configs:

      - targets: ['server_ip:9090']

Step 3: Change the ownership of the file to the Prometheus user.

sudo chown prometheus:prometheus /etc/prometheus/prometheus.yml

Setup Prometheus Service File:

Step 1: Create a Prometheus service file.

sudo vi /etc/systemd/system/prometheus.service

Step 2: Copy the following content to the file.

[Unit]

Description=Prometheus

Wants=network-online.target

After=network-online.target

[Service]

User=prometheus

Group=prometheus

Type=simple

ExecStart=/usr/local/bin/prometheus \

    --config.file /etc/prometheus/prometheus.yml \

    --storage.tsdb.path /var/lib/prometheus/ \

    --web.console.templates=/etc/prometheus/consoles \

    --web.console.libraries=/etc/prometheus/console_libraries

[Install]

WantedBy=multi-user.target

Step 3: Reload the systemd service to register the Prometheus service and start the Prometheus service.

sudo systemctl daemon-reload

sudo service prometheus start

service prometheus status

sudo systemctl enable prometheus

sudo systemctl status prometheus

Step 4: Access Prometheus Web UI

http//:ec2serverip:9090

What is DevOps? Hey Folks, We live in an era where machines and their Intelengency rule over Human Efforts and make our day-to-day tasks easy. Where we are now completely dependent upon machines for any small or big task. So all the backend processes used in the working of any Machines, Applications, or Websites need to be real quick and fast. For example, you prepared an application or a machine but it's the hardware or just a view. What makes it run is its software (Soul of any Machines, Application, or Website). Now, what is Software? Software is nothing but a collection of data or instructions that tell the Application (Computer, Machines, Hardware, Website, etc...) how to work. Software Life Cycle..! Okay so now you know what is software, but every software is first needed to be developed according to the requirement, and then it goes for testing if testing is failed it again goes for the redevelopment once the testing process is tested successfully then i

Microservices in GraphQL Hey Family, As you already know with the title we are going to discuss, Trending topics of 2020 today. I promise today's Blog would change your thinking about how Projects are currently working and how they will work in the coming time. Hold it and stay tuned for the below-mentioned topics: What is Microservices Architecture? GraphQL with Microservice using Docker Construct an application as a set of services that are, Highly maintainable and testable. Loosely coupled.  Deployed, Maintained and Developed independently From the starting separated by service boundaries which make it more convenient to scale up the development effort if needed Making it more convenient to choose the technology stack (programming databases, languages, etc.) which is best suited for the required service Monolithic vs Microservices Monolithic Monolithic Architecture Single Code Base Often time-consuming and confusing Difficult deployment with maintenance windo
