NetBox supports optionally exposing native Prometheus metrics from the application. [Prometheus](https://prometheus.io/) is a popular time series metric platform used for monitoring.
NetBox exposes metrics at the `/metrics` HTTP endpoint, e.g. `https://netbox.local/metrics`. Metric exposition can be toggled with the `METRICS_ENABLED` configuration setting. Metrics are exposed by default.

When deploying NetBox in a multiprocess mannor--such as using Gunicorn as recomented in the installation docs--the Prometheus client library requires the use of a shared directory
to collect metrics from all the worker processes. This can be any arbitrary directory to which the processes have read/write access. This directory is then made available by use of the
`prometheus_multiproc_dir` environment variable.
This can be setup by first creating a shared directory and then adding this line to the `[program:netbox]` section of the supervisor config file.
