Install Sensu Monitoring on Ubuntu 20.04

In this tutorial, we will show you how to install Sensu Monitoring on Ubuntu 20.04 LTS. For those of you who didn’t know, Sensu Go is the latest version of Sensu. It is an open-source, full-stack monitoring tool suitable for any kind of dynamic operating environment. It is a simple, scalable, and malleable framework that helps you compose the monitoring system you need.

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 of the Sensu Go monitoring on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Install Sensu Monitoring on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install curl gnupg unzip wget

Step 2. Installing Sensu Monitoring on Ubuntu 20.04.

Sensu Go provides us with a script that adds its repository to our system in a very convenient way:

curl -s https://packagecloud.io/install/repositories/sensu/stable/script.deb.sh | sudo bash

Once the script is downloaded and executed, you can go and begin installing Sensu packages:

sudo apt install sensu-go-backend

After installing, now we download the configuration file in its default configure directory:

sudo curl -L https://docs.sensu.io./sensu-go/latest/files/backend.yml -o /etc/sensu/backend.yml

Next, manage Sensu as a system service. So, start it, enable it and check the status of the service:

sudo systemctl start sensu-backend
sudo systemctl enable sensu-backend

Then, you need to install sensuctl by running:

sudo apt install sensu-go-cli

Once done, you have to configure it by running:

$ sensuctl configure
? Authentication method: username/password
? Sensu Backend URL: http://127.0.0.1:8080
? Namespace: default
? Preferred output format: tabular
? Username: admin
? Password: ******

Step 3. Accessing Sensu Monitoring Web Interface.

You may now access your Uchiwa dashboard using http://your-ip-server:3000. You should see the Sensu dashboard on the following screen:
