Introduction

Sensu is an open-source monitoring solution designed to help you monitor your entire infrastructure efficiently. By installing Sensu on Rocky Linux 9, you can gain insights into your systems, ensuring that everything runs smoothly. This setup is particularly useful when integrated with a Windows VPS UK for enhanced performance and scalability.

Prerequisites

• Rocky Linux 9 server with root access
• Basic knowledge of Linux commands
• Internet connection for downloading packages

Step 1: Install Required Dependencies

Before installing Sensu, you need to ensure that your system is up to date and has the necessary dependencies. Run the following commands:

sudo dnf update -y
sudo dnf install -y curl wget

Step 2: Add the Sensu Repository

Next, you need to add the Sensu repository to your system. Create a new repository file:

sudo nano /etc/yum.repos.d/sensu.repo

Then, add the following content to the file:

[sensu]
name=Sensu Repository
baseurl=https://repositories.sensu.io/6/stable/centos/9/x86_64/
gpgcheck=1
gpgkey=https://repositories.sensu.io/6/stable/centos/9/x86_64/RPM-GPG-KEY
enabled=1

Step 3: Install Sensu Backend

With the repository added, you can now install the Sensu backend:

sudo dnf install -y sensu-go-backend

After the installation is complete, start and enable the Sensu backend service:

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

Step 4: Configure Sensu Backend

To configure the Sensu backend, you will need to set up an admin password. Run the following command to generate a password:

sudo sensuctl configure -n -p your_password -u admin -d --namespace default

Replace your_password with a strong password of your choice.

Step 5: Install Sensu Agent

To monitor your servers, you will need to install the Sensu agent on each system you want to monitor. Install the Sensu agent by running:

sudo dnf install -y sensu-go-agent

Once installed, start and enable the agent:

sudo systemctl start sensu-agent
sudo systemctl enable sensu-agent

Step 6: Configure Sensu Agent

Next, configure the Sensu agent to connect to the backend. Edit the configuration file:

sudo nano /etc/sensu/sensu-agent.yml

Update the backend URL:

backend-url: ws://your_backend_ip:8081

Replace your_backend_ip with the IP address of your Sensu backend.

Step 7: Access the Sensu Dashboard

You can access the Sensu dashboard by navigating to http://your_backend_ip:3000 in your web browser. Log in using the admin credentials you set up earlier.
