monitor linux server using prometheus

Login to your aws and ssh the key into the perminal

install prometheus node exporter

run this command curl -LO https://github.com/prometheus/node_exporter/releases/latest/download/node_exporter-linux-amd64.tar.gz

extract the downloaded terball

### extract the downloaded terball done ### move the binary to a directory in your PATH

create a systemd service file for node exporter by running the command " sudo nano /etc/systemd/system/node_exporter.service

past in the code inside the file

[Unit] Description=Prometheus Node Exporter After=network.target

[Service] User=nobody ExecStart=/usr/local/bin/node_exporter Restart=always

[Install] WantedBy=multi-user.target

"

Reload systemd and start the node exporter service to the following commands

sudo systemctl daemon-reload sudo systemctl start node_exporter sudo systemctl enable node_exporter

verify that node exporter is runing with this command

confirm node exporter is accessible by visiting http://http://18.215.150.215:9100/

on this part we need to open the prometheus configurations file called (prometheus.yml)

run this command sudo nano /etc/prometheus/prometheus.yml

Add a new scrape job for node exporter

Now we have to give permission to the file

we need to save the file and restart the prometheus to apply the changes

run this command "sudo systemctl restart prometheus"

verify the port "sudo ss -tlnp | grep 9090"

Access the prometheus web interface http://18.215.150.215:9090/
