arris-scrape

arris-scrape will read from Arris's modem web page and output Prometheus-style metrics as a one-shot or as a server.

Tested only on an Arris SURFboard SB8200.

To use:

go install stevenandbonnie.com/arris-scrape@latest
arris-scrape -passwd $PASSWD

Downstream metrics:

1. downstream_bonded_channels_frequency_hz
2. downstream_bonded_channels_power_dbmv
3. downstream_bonded_channels_snr_mer_db
4. downstream_bonded_channels_corrected
5. downstream_bonded_channels_uncorrectables

Upstream metrics:

1. upstream_bonded_channels_frequency_hz
2. upstream_bonded_channels_width_hz
3. upstream_bonded_channels_power_dbmv

It's intended to be run repeatedly by another tool. For example, for Telegraf:

[[inputs.exec]]
  name_override = "modem"
  commands = ["arris-scrape -passwd 'my password'"]
  data_format = "prometheus"
  interval = "60s"
  timeout = "30s"

Pass in a flag like -http-addr=:5000 to run in server mode.
