+# Prometheus Metrics
+
+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 not exposed by default.
+
+## Metric Types
+
+NetBox makes use of the [django-prometheus](https://github.com/korfuri/django-prometheus) library to export a number of different types of metrics, including:
+
+- Per model insert, update, and delete counters
+- Per view request counters
+- Per view request latency histograms
+- Request body size histograms
+- Response body size histograms
+- Response code counters
+- Database connection, execution, and error counters
+- Cache hit, miss, and invalidation counters
+- Django middleware latency histograms
+- Other Django related metadata metrics
+
+For the exhaustive list of exposed metrics, visit the `/metrics` endpoint on your NetBox instance.
+
+## Multi Processing Notes
+
+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 (with the appropriate directory) to the `[program:netbox]` section of the supervisor config file.
+
+```
+environment=prometheus_multiproc_dir=/tmp/prometheus_metrics

-When a base serializer includes one or more nested serializers, the hierarchical structure precludes it from being used for write operations.

+* HOST - Name or IP address of the Redis server (use `localhost` if running locally)
+* PORT - TCP port of the Redis service; leave blank for default port (6379)
+* PASSWORD - Redis password (if set)
+* DATABASE - Numeric database ID for webhooks

+    'SSL': False,
+}

+
+!!! note:
+    If you were using these settings in a prior release with webhooks, the `DATABASE` setting remains the same but
+    an additional `CACHE_DATABASE` setting has been added with a default value of 1 to support the caching backend. The
+    `DATABASE` setting will be renamed in a future release of NetBox to better relay the meaning of the setting. 
+
+!!! warning:
+    It is highly recommended to keep the webhook and cache databases seperate. Using the same database number for both may result in webhook
+    processing data being lost in cache flushing events.
