How to install and configure Prometheus with Grafana on Ubuntu 18.04 LTS

Prometheus is a free and open source programming environment that permits us to gather measurements from our applications and stores them in an information base, particularly a period arrangement based DB. It is an incredible observing framework reasonable for dynamic conditions. Prometheus is written in Go and use inquiry language for information preparing. Prometheus gives measurements of CPU, memory, plate utilization, I/O, network insights, MySQL worker and Nginx.

In this post, We will install and configure  Prometheus – Monitoring system & time series database on Ubuntu 18.04  LTS.

Step 1: Update the System 

You need to update the ubuntu current repository server by using the given command.

sudo apt-get update

Step 2: Add Prometheus Repository 

Once the ubuntu system up to date So then you need to add the prometheus repository by using the command.

sudo apt-get update
sudo apt-get install prometheus prometheus-node-exporter prometheus-pushgateway prometheus-alertmanager -y

Here we are installing all the required package for the prometheus along with aletmanager, node-expoter and pushgateway.

Get the prometheus service status by using the given command.

sudo systemctl status prometheus

Step 4: UFW Rules

After installation of the packages, We need to open the required port by using the command.

sudo ufw status
sudo ufw allow 9090

Step 5: Accessing Web Panel

You need to open the browser with http://localhost:9090 or http://IP_Address:9090 if everything okay, So then you should get web page like this.

 

 

cd /tmp
sudo wget https://dl.grafana.com/oss/release/grafana_5.4.3_amd64.deb
