Installing Sensu on Kali Linux

Sensu is an open-source monitoring framework that helps in monitoring and alerting various parts of your infrastructure. In this tutorial, we'll go through the step-by-step process of installing Sensu on Kali Linux.

Prerequisites:

  • Kali Linux installed
  • Root access or a user with sudo privileges

Step 1: Add Sensu repository

The first step is to add the Sensu repository to the list of repositories on our system. We'll do this by creating a new file in the /etc/apt/sources.list.d/ directory with the Sensu repository URL.

  1. Open the terminal
  2. Run the following command to create a new file in /etc/apt/sources.list.d/ directory:
sudo nano /etc/apt/sources.list.d/sensu.list
  1. Add the following line to the file:
deb https://packagecloud.io/sensu/stable/debian/ buster main

  1. Press Ctrl + O to save the changes and Ctrl + X to exit Nano.

  2. Run the following command to add the Sensu repository key:

curl -s https://packagecloud.io/gpg.key | sudo apt-key add -

Step 2: Install Sensu

Now that we have added the Sensu repository to our system, we can use apt-get to install Sensu.

  1. Update the package list:
sudo apt-get update
  1. Install Sensu:
sudo apt-get install sensu

Step 3: Configure Sensu

The Sensu installation process will create a default configuration located at /etc/sensu/.

  1. Navigate to the Sensu configuration directory:
cd /etc/sensu/
  1. Rename the config.json.example file to config.json:
sudo mv config.json.example config.json
  1. Enable the Sensu service:
sudo systemctl enable sensu.service
  1. Start the Sensu service:
sudo systemctl start sensu.service

Step 4: Verify installation

To verify that the installation was successful, we can check the version of Sensu:

sensu-client --version

This will output the version of Sensu installed.

Congratulations! You have installed Sensu on Kali Linux. Now you can start configuring Sensu to monitor and alert on various parts of your infrastructure.
