# This plugin graphs the following values of the ARRIS TM502G cable
|
|
# modem:
|
|
#
|
|
# * upstream and downstream powers
|
|
# * downstream signal-to-noise ratio
|
|
#
|
|
# The values are retrieved from the cable modem's status web pages at
|
|
# 192.168.100.1. So, this plugin must be installed on a munin node
|
|
# which can access those pages.
|
|
#
|
|
# Symlink this plugin into the node's plugins directory (like
|
|
# /etc/munin/plugins) as arris-tm502g_power for the powers, and
|
|
# arris-tm502g_snr for the SNR.
