      prometheus-node-exporter-lua: lower case bssid label value in wifi exporter · 445d8927
      Martin Weinelt authored 
      

To allow cross matching bssids between different exporters we need to
use the same case, as label matching is case senstive.

      prometheus-node-exporter-lua: fix corner case in hostapd_stations · a1b145ab
      Martin Weinelt authored 
      

There was a corner case, when a vif had no stations, that
evaluate_metrics for a station that was nil and had no collected metrics
would have been called.

Comment the code, to make it easier to understand and follow, and
simplify some variable names along the way.

      prometheus-node-exporter-lua: normalize metric names in hostapd_stations · a9859616
      Martin Weinelt authored 
      Normalizes metrics according to the Prometheus upstream metric
guidelines available at https://prometheus.io/docs/practices/naming/

.

Drops the `hostapd_station_wpa` metric, because it is misleading, as it
is not a differentiator between WPA versions, like one could be led to
assume.

Exposes more flags in a more consistent manner. Their metric was
previously only exposed if the flag was present, but not if it wasn't.
The same applies issue was fixed with regards to vht caps.

After this commit the following breaking changes are in place:

- All flags have been moved below `hostapd_station_flags_$flagname`:
  - `hostapd_station_ht` is now `hostapd_station_flag_ht`
  - `hostapd_station_mfp` is now `hostapd_station_flag_mfp`
  - `hostapd_station_vht` is now `hostapd_station_flag_vht`
  - `hostapd_station_wmm` is now `hostapd_station_flag_wmm`

- New flags have been exposed:
  - `hostapd_station_flag_he` for high-efficency connections
  - `hostapd_station_flag_short_preamble` for short preamble connections
  - `hostapd_station_flag_auth` for authentication state
  - `hostapd_station_flag_assoc` for association state

- Some metrics have had their unit normalized to the SI base unit or
  embedded into the metrics name:
  - `hostapd_station_inactive_msec` is now
    `hostapd_station_inactive_seconds`, the value is still float64 and
    as such has enough precision anyway, but becomes easier to reason
    about
  - `hostapd_station_connected_time` has been renamed to
    `hostapd_station_connected_seconds_total` so the unit, as well as
    the nature of the counter is reflected
  - `hostapd_station_signal` now includes its unit and is therefore
    named `hostapd_station_signal_dbm`

- The packet counter metrics have been normalized to what the node
  exporter uses, so it is more in line with the defaults in the
  Prometheus ecosystem:
  - `hostapd_station_rx_packets` is now
    `hostapd_station_receive_packets_total`
  - `hostapd_station_rx_bytes` is now
    `hostapd_station_receive_bytes_total`
  - `hostapd_station_tx_packets` is now
    `hostapd_station_transmit_packets_total`
  - `hostapd_station_tx_bytes` is now
    `hostapd_station_transmit_bytes_total`
