# -*- python -*-
# 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.

#
# Munin plugin for the D-link DIR-655 router
#
# This plugin can graph # of wifi clients, # of DHCP clients, collisions & errors for all network interfaces, dropped packets for all interfaces, and both transmit and receive rates for all interfaces of the router.
#
# Author: David Reitz
#
# 1. Copy script to a Linux server on your network.
# 2. Create symlink. (ln -s /path/to/dlink_dir655 /etc/munin/plugins/dlink_dir655)
# 3. Edit plugin configuration for this script (vi /etc/munin/plugin-conf.d/munin-node) and add:
# [dlink_dir655]
# host_name dir655
# env.router_password password
# env.router_ip_address 10.0.0.1
# 4. Edit munin configuration to point to itself to gather the data from your router (vi /etc/munin/munin-conf.d/munin) and add:
# [dir655]
# address 127.0.0.1
# use_node_name no
# 5. Modify the 'password' and 'router_path' variables below to reflect the correct password for the 'User' user on your D-link DIR-655 router and to reflect the correct IP address of your router (this *MUST* be on your local subnet/LAN).
#
# NOTICE 1: This is the first Ruby script I've written (as well as being my first Munin plugin), so I consider this a bit of a hack. Just letting you know ahead of time. :)
#
# NOTICE 2: I provide this script *as-is*. Use at your own risk! I thought other people may find this script useful/interesting but have no plans to support it for anyone else.
#
# Many thanks go to Clarke Brunsdon for his code listed at http://clarkebrunsdon.com/2010/12/the-dlink-dir-655-hash-changes/!!! This really helped me out!

# This plugin graphs the following values of the Motorola SB6141 cable
# modem:
#
# * upstream and downstream power levels
# * downstream signal to noise ratio
# * downstream signal statistics (codeword counts)
#
# 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.
#
# To install, place this plugin in the node's plugins directory,
# /etc/munin/plugins and restart munin-node.
#
# Developed and tested with firmware SB_KOMODO-1.0.6.16-SCM00-NOSH
# (build time Feb 16 2016 11:28:04), hardware version 7.0, boot
# version PSPU-Boot(25CLK) 1.0.12.18m3.
#
# Requires the multigraph and dirtyconfig capabilities available in
# munin 2.0 and newer.
