Overview#

Steps#

Here are the simple steps how to do it :

Grafana#

• Wget & Install Grafana File

TIP

For latest guide installation, you can always refer to grafana documentation

sudo apt-get install -y apt-transport-https software-properties-common wget
sudo mkdir -p /etc/apt/keyrings/
wget -q -O - https://apt.grafana.com/gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/grafana.gpg > /dev/null
echo "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
sudo apt-get update
sudo apt-get install grafana

• Start your Grafana service

TIP

Keep in mind grafana by default is using port 3000

sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl status grafana-server

Your grafana service will show running in systemctl. When running, your installation is successfull. Now, onto the next step.

Prometheus#

• Grab prometheus file

TIP

For the latest version, you can always refer to prometheus repo

sudo wget https://github.com/prometheus/prometheus/releases/download/v3.1.0/prometheus-3.1.0.linux-amd64.tar.gz

• Unpack the file

sudo tar vxf prometheus*.tar.gz

• Add new user for prometheus

sudo groupadd --system prometheus
sudo useradd -s /sbin/nologin --system -g prometheus prometheus

• Add new directory for prometheus

sudo mkdir /etc/prometheus
sudo mkdir /var/lib/prometheus
cd prometheus*/

• Add new directory for prometheus

sudo mv prometheus /usr/local/bin
sudo mv promtool /usr/local/bin
sudo mv console* /etc/prometheus
sudo mv prometheus.yml /etc/prometheus

• Change the ownerships

sudo chown prometheus:prometheus /usr/local/bin/prometheus
sudo chown prometheus:prometheus /usr/local/bin/promtool
sudo chown prometheus:prometheus /etc/prometheus
sudo chown -R prometheus:prometheus /etc/prometheus/consoles
sudo chown -R prometheus:prometheus /etc/prometheus/console_libraries
sudo chown -R prometheus:prometheus /var/lib/prometheus

• Edit prometheus.yml using nano

sudo nano /etc/prometheus/prometheus.yml

• Add this configuration to prometheus.yml

global:
  scrape_interval: 15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']

• Add systemd service for prometheus using nano

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

• Add systemd configuration below for prometheus.service

[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

• Start Prometheus Service

sudo systemctl daemon-reload
sudo systemctl enable prometheus
sudo systemctl start prometheus
sudo systemctl status prometheus

Node Exporter#

Node Exporter is part of Prometheus. It use for export machine metrics such as CPU, Memory, Disk, and more.

• Execute this command

sudo wget https://github.com/prometheus/node_exporter/releases/download/v1.8.2/node_exporter-1.8.2.linux-amd64.tar.gz
sudo tar xzf node_exporter-1.8.2.linux-amd64.tar.gz
sudo rm -rf node_exporter-1.8.2.linux-amd64.tar.gz
sudo mv node_exporter-1.8.2.linux-amd64 /etc/node_exporter

• Create systemd service for node exporter

sudo nano /etc/systemd/system/node_exporter.service

• Add this config to node_exporter.service

[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target

[Service]
ExecStart=/etc/node_exporter/node_exporter
Restart=always

[Install]
WantedBy=multi-user.target

• Start Node Exporter service

sudo systemctl daemon-reload
sudo systemctl enable node_exporter
sudo systemctl restart node_exporter
sudo systemctl status node_exporter

Just Last Step#

• For the next step, just make sure you pointing the prometheus service inside your data source grafana. Usually, it’s on port 9090.
• After that, add new dashboard using new data source and here you go. You able to start monitor your system
• Enjoy!
