How to install Sensu on CentOS 7

Sensu is a monitoring router for Linux operating systems such as CentOS 7. It monitors “check” scripts and passes their results to the corresponding handler scripts when the specified conditions are met. Checking the status of a service such as Apache is one of the most common uses of Sensu. Installing Sensu requires you to install its supporting applications, which include Erlang, RabbitMQ and Redis. You’ll also need to view Sensu data with an application such as Uchiwa, which is a web-based dashboard for Sensu. The primary challenge with this procedure is locating the current software packages for your system.

To set this up, you’ll need a live Linux server (that you can tweak) with a dedicated IP address and a way to connect to it. We recommend a GoDaddy Virtual Private Server if you’re just getting started, or a full dedicated server if you’re ready to take total control. To connect to your server, you’ll need some kind of an SSH client. Google it, or try PuTTY (Windows) or Terminal (Mac).

5. Install and start the Uchiwa services.

6. Verify that Sensu is running.

Open a browser window and enter the default address and port number for Sensu, which is localhost:3000. This page should appear similar to the following screenshot if Sensu is running:
