Sensu is an open-source monitoring framework for modern applications and infrastructure. In this tutorial, we will be installing Sensu on POP! OS, which is a Linux-based operating system.
Before we start, ensure that you have the following prerequisites:
Follow the steps below to install Sensu on your POP! OS system:
To install Sensu, you will need to install RabbitMQ, Redis, and Erlang dependencies. You can install these dependencies by running the following command in your terminal:
$ sudo apt install -y rabbitmq-server redis erlang erlang-dev gcc libc-dev make git
Once the dependencies have been installed, you can proceed to download the Sensu package from the Sensu.io website. You can use the following command to download the latest Sensu package:
$ curl -LO https://sensu.global.ssl.fastly.net/apt/pool/main/s/sensu/sensu_1.9.1~dfsg-1_amd64.deb
After downloading the package, you can install it using the dpkg command. Run the following command to install Sensu:
$ sudo dpkg -i sensu_1.9.1~dfsg-1_amd64.deb
After installing Sensu, you will need to configure it. You can modify the Sensu configuration file at /etc/sensu/config.json. You may want to change some of the default settings such as RabbitMQ and Redis connection strings, Sensu API settings, and more.
Once you have configured Sensu, you can start it using the following command:
$ sudo systemctl start sensu-api sensu-server sensu-client
To verify that Sensu is running correctly, you can run the following command:
$ sudo sensuctl check list
This command will display a list of Sensu checks that have been defined. If the command returns no output, Sensu is not running correctly.
Congratulations! You have successfully installed and configured Sensu on your POP! OS system. Sensu can now be used to monitor and manage your applications and infrastructure.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
