ag241-adsl
Name
ag241-adsl - retrieve connection statistics from the web admin interface of a Linksys AG241v2 ADSL modem
Description
Data is extracted from the http://modemaddress/ADSLCStatus.htm page.
This plugin has only been tested on a Debian testing system.
This modem also has some basic SNMP support so you can configure it as per the instructions on the munin wiki:
http://munin.projects.linpro.no/wiki/Using_SNMP_plugins
By default the SNMP server is disabled, you can enable it in the web admin. You will need to set up the “virtual node” configuration as detailed for snmp plugins.
Configuration
The plugin requires some configuration in /etc/munin/plugin-conf.d/ag241_MODEMADDRESS e.g.
[ag241_vocume.stargate_*]
env.user admin
env.pass password
#env.port 80
Once you have the above config set you will need to symlink the plugin to
/etc/munin/plugins/ag241_MODEMADDRESS_syncrate
/etc/munin/plugins/ag241_MODEMADDRESS_attenutation
/etc/munin/plugins/ag241_MODEMADDRESS_noise
Restart munin-node afterwards.
Hopefully in 20-30mins you will have some nice graphs.
