+
+## Overview
+
+Collect information about FreeBSD firewall.
+
+The plugin uses RAW socket to communicate with kernel and collect data.
+
+This collector is supported on all platforms.
+
+This collector supports collecting metrics from multiple instances of this integration, including remote instances.
+
+
+### Default Behavior
+
+#### Auto-Detection
+
+This integration doesn't support auto-detection.
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per ipfw instance
+
+Theese metrics show FreeBSD firewall statistics.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| ipfw.mem | dynamic, static | bytes |
+| ipfw.packets | a dimension per static rule | packets/s |
+| ipfw.bytes | a dimension per static rule | bytes/s |
+| ipfw.active | a dimension per dynamic rule | rules |
+| ipfw.expired | a dimension per dynamic rule | rules |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
