#
#Multigraph munin plugin to monitor Ubiquiti AirOS devices various parameters.
#
#To use this plugin, copy it to the munin's plugin directory (eg. /usr/share/munin/plugins)
#under the name "ubiquiti_airos_". Don't change this filename! Follow these steps:
#
#1. Give names to your devices, in fqdn style. Like "apo.wlan" or "cli.wlan". To make the
# system understand that, in your /etc/hosts file, add to localhost these names which corespond
# to your devices:
# 127.0.0.1 localhost apo.wlan cli.wlan
# Don't be fooled by 127.0.0.1, this is the localhost IP address, since munin will handle
# them as virtual nodes!
#
#2. Then symlink it to munin's configured plugins directory (eg. /etc/munin/plugins) with names
# according to the devices you wish to monitor, eg:
# ubiquiti_airos_apo.wlan
# ubiquiti_airos_cli.wlan
#
# Important: make sure to use the same names in your symlinks and other config places!
#
#3. In /etc/munin/plugin-conf.d/munin-node add the following, to be able to contact
# those devices via telnet (obviously replacing these with your own data):
#
# [ubiquiti_airos_apo.wlan]
# env.Name AccessPoint
# env.Host 192.168.2.2
# env.TelnetPort 23
# env.TelnetUser foobar
# env.TelnetPass raboof
#
# [ubiquiti_airos_cli.wlan]
# env.Name Client
# env.Host 192.168.2.3
# env.TelnetPort 23
# env.TelnetUser foobar
# env.TelnetPass raboof
#
#4. In /etc/munin/munin.conf add them as new virtual nodes:
#
# [apo.wlan]
# address 127.0.0.1
#
# [cli.wlan]
# address 127.0.0.1
#
#5. Restart the munin node by 'service munin-node restart'.
#
# If all went well, after 5 minutes or so you should have two additional nodes listed
# on the Web Interface of munin.
#
#Plugin based on aramsey's script, which is based on a MicroTik plugin, see for more info see this link:
#http://community.ubnt.com/t5/NanoStation-and-Loco-Devices/SNMP-data-for-NF-dBm/m-p/39070/highlight/true#M11372
#
#Tested & working with munin v.2.0.14 and AirOS v5.5.4.
