In this tutorial, we will show you how to install Prometheus on Ubuntu 16.04 LTS. For those of you who didn’t know, Prometheus is an excellent open-source monitoring system which allows us to collect metrics from our applications and stores them in a database, especially a time-series based DB. The biggest advantage of Prometheus is the query language it provides for data processing.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Prometheus open-source monitoring on an Ubuntu 16.04 Xenial Xerus server.

Step 2. Installing Nginx web server.
The first thing we must do is install NGINX on the system:

Next, we’re ready to install all the required packages in your system:
apt-get update apt-get install prometheus prometheus-node-exporter prometheus-pushgateway prometheus-alertmanager
Once installed, you can confirm that the app is running by using this command:
service prometheus start service prometheus status
