# 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.

|
|
# 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!
