Runs `iw dev` searching for interfaces that have `type AP`. + + From the same output it collects the SSIDs each AP supports by looking for lines `ssid NAME`. + + Example: +```sh +# iw dev +phy#0 + Interface wlan0 + ifindex 3 + wdev 0x1 + addr 7c:dd:90:77:34:2a + ssid TSAOUSIS + type AP + channel 7 (2442 MHz), width: 20 MHz, center1: 2442 MHz +``` + + +2. For each interface found, it runs `iw INTERFACE station dump`. + + From the output is collects: + + - rx/tx bytes + - rx/tx packets + - tx retries + - tx failed + - signal strength + - rx/tx bitrate + - expected throughput + + Example: + +```sh +# iw wlan0 station dump +Station 40:b8:37:5a:ed:5e (on wlan0) + inactive time: 910 ms + rx bytes: 15588897 + rx packets: 127772 + tx bytes: 52257763 + tx packets: 95802 + tx retries: 2162 + tx failed: 28 + signal: -43 dBm + signal avg: -43 dBm + tx bitrate: 65.0 MBit/s MCS 7 + rx bitrate: 1.0 MBit/s + expected throughput: 32.125Mbps + authorized: yes + authenticated: yes + preamble: long + WMM/WME: yes + MFP: no + TDLS peer: no +``` + +3. For each interface found, it creates 6 charts: + + - Number of Connected clients + - Bandwidth for all clients + - Packets for all clients + - Transmit Issues for all clients + - Average Signal among all clients + - Average Bitrate (including average expected throughput) among all clients + +## Configuration + +You can only set `ap_update_every=NUMBER` to `/etc/netdata/charts.d/ap.conf`, to give the data collection frequency. +To edit this file on your system run `/etc/netdata/edit-config charts.d/ap.conf`. + +## Auto-detection + +The plugin is able to auto-detect if you are running access points on your linux box. |
