Access Point monitoring with Netdata¶
ap collector visualizes data related to access points.
Example Netdata charts¶
How it works¶
It does the following:
iw devsearching for interfaces that have
From the same output it collects the SSIDs each AP supports by looking for lines
# 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
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
# 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
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
charts.d/ap.conf configuration file using
edit-config from the your agent’s config
directory, which is typically at
cd /etc/netdata # Replace this path with your Netdata config directory, if different sudo ./edit-config charts.d/ap.conf
You can only set
ap_update_every=NUMBER to change the data collection frequency.
The plugin is able to auto-detect if you are running access points on your linux box.
