List of Plugins

The MadWifi plugin collects information about Atheros wireless LAN chipsets from the MadWifi driver. It uses the /sys filesystem to identify cards handled by this driver automatically but can be configured manually, too. Because very many statistics are available, an advanced selection mechanism is provided.

[edit] Special statistics

Name Description Default
node_octets RX and TX data count (per node) enabled
node_rssi Received signal strength indication (RSSI) (per node) enabled
node_tx_rate used TX rate (per node) enabled
ath_nodes the number of associated nodes (per interface) enabled

[edit] Node statistics

All the following statistics are collected per node, i. e. there will be one file for each node associated with the interface. If the interface acts as an Access Point (AP), there is one node per one associated station. If the interface acts as an Station (sta), there is an node representing AP with which the station is associated.
