Installation of Grafana, Prometheus and Node Exporter on Ubuntu Server

Grafana, Prometheus and Node Exporter Setup

Install Grafana

1) Download the Latest Grafana Version

sudo apt update

sudo apt-get install -y adduser libfontconfig1 musl

wget https://dl.grafana.com/enterprise/release/grafana-enterprise_10.3.1_amd64.deb

sudo dpkg -i grafana-enterprise_10.3.1_amd64.deb

2) Start the Service

systemctl daemon-reload

systemctl start grafana-server

systemctl status grafana-server

sudo systemctl enable grafana-server.service

3) Access Grafana Web Interface

Open security port 3000

<ip_address>:3000

Install Prometheus

1) Create a System User for Prometheus

sudo groupadd --system prometheus

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

2) Create Directories for Prometheus

sudo mkdir /etc/prometheus

sudo mkdir /var/lib/prometheus

3) Download Prometheus and Extract Files

wget https://github.com/prometheus/prometheus/releases/download/v2.43.0/prometheus-2.43.0.linux-amd64.tar.gz

tar vxf prometheus*.tar.gz

4) Navigate to the Prometheus Directory

cd prometheus*/

Configuring Prometheus

1) Move the Binary Files & Set Owner

sudo mv prometheus /usr/local/bin

sudo mv promtool /usr/local/bin

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

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

2) Move the Configuration Files & Set Owner

sudo mv consoles /etc/prometheus

sudo mv console_libraries /etc/prometheus

sudo mv prometheus.yml /etc/prometheus

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

3) Set the targets

sudo nano /etc/prometheus/prometheus.yml

4) Create Prometheus Systemd Service and add the following code inside

sudo nano /etc/systemd/system/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

5) Reload Systemd

sudo systemctl daemon-reload

6) Start Prometheus Service

sudo systemctl enable prometheus

sudo systemctl start prometheus

7) Check Prometheus Status

sudo systemctl status prometheus

8) Access Prometheus Web Interface

Open security port 9090

localhost:9090 or <ip_address>:9090

Download Node Exporter

1) Download the Node Exporter binary

wget https://github.com/prometheus/node_exporter/releases/download/v1.0.1/node_exporter-1.0.1.linux-amd64.tar.gz

2) Create User

sudo groupadd -f node_exporter

sudo useradd -g node_exporter --no-create-home --shell /bin/false node_exporter

sudo mkdir /etc/node_exporter

sudo chown node_exporter:node_exporter /etc/node_exporter

3) Unpack Node Exporter Binary

tar -xvf node_exporter-1.0.1.linux-amd64.tar.gz

mv node_exporter-1.0.1.linux-amd64 node_exporter-files

4) Install Node Exporter

sudo cp node_exporter-files/node_exporter /usr/bin/

sudo chown node_exporter:node_exporter /usr/bin/node_exporter

5) Setup Node Exporter Service

sudo vi /usr/lib/systemd/system/node_exporter.service

Add the following code

[Unit]
Description=Node Exporter
Documentation=https://prometheus.io/docs/guides/node-exporter/
Wants=network-online.target
After=network-online.target

[Service]
User=node_exporter
Group=node_exporter
Type=simple
Restart=on-failure
ExecStart=/usr/bin/node_exporter \
  --web.listen-address=:9200

[Install]
WantedBy=multi-user.target

sudo chmod 664 /usr/lib/systemd/system/node_exporter.service

6) Reload systemd and Start Node Exporter

sudo systemctl daemon-reload

sudo systemctl start node_exporter

sudo systemctl status node_exporter

sudo systemctl enable node_exporter.service

7) Verify Node Exporter is Running

Open security port 9200

http://<ip-address>:9200/metrics

8) Add target in the prometheus

Add the following code inside the prometheus.yml

 - job_name: "node_exporter"

      # metrics_path defaults to '/metrics'
      # scheme defaults to 'http'.

    static_configs:
      - targets: ["<ip-address>:9200"]
