Prometheus exporter for NGINX Unit metrics

The NGINX Unit control API includes a /status endpoint for usage statistics. This is a solution for exposing these metrics in Prometheus format.

The application (run by Unit) queries the /status URI on the control socket and converts the JSON response into Prometheus text format. PHP and Python implementations are available.

These instructions assume an existing Unit installation with a working configuration. We will add a new listener on the default prometheus port (9090) and route it directly to the Prometheus app.

Step 0. Install the preferred Unit language module (unit-php or unit-python)

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
