https:\/\/garage.godaddy.com\/tech\/config\/install-sensu-centos7\/<\/a><\/p>\n

Sensu is a monitoring router for Linux operating systems such as CentOS 7. It monitors \u201ccheck\u201d 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\u2019ll 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.<\/p>\n

To set this up, you\u2019ll 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<\/a> if you\u2019re just getting started, or a full dedicated server<\/a> if you\u2019re ready to take total control. To connect to your server, you\u2019ll need some kind of an SSH client. Google it, or try PuTTY<\/a> (Windows) or Terminal<\/a> (Mac).<\/p>\n
