For each interface that is of `type AP`, it then runs `iw INTERFACE station dump` and collects statistics. + +This collector is only supported on the following platforms: + +- Linux + +This collector only supports collecting metrics from a single instance of this integration. + + +### Default Behavior + +#### Auto-Detection + +The plugin is able to auto-detect if you are running access points on your linux box. + +#### 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.
