#
# Multigraph munin plugin to monitor Ubiquiti AirOS F (airFiber) devices various parameters. It needs
# Perl's Net::Telnet or Net::OpenSSH to be able to connect.
#
# To use this plugin, copy it to the munin's plugin directory (eg. /usr/share/munin/plugins)
# under the name "ubiquiti_airfiber_". Don't change this filename! Follow these steps:
#
# 1. Give names to your devices, in fqdn style. Like "master.wlan" or "slave.wlan". To make the
# system understand that, add them to your /etc/hosts file, like below:
# 192.168.2.2 master.wlan
# 192.168.2.3 slave.wlan
# You could of course add these to your network's local DNS server if you want to.
#
# 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_airfiber_master.wlan
# ubiquiti_airfiber_slave.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_master.wlan]
# user root # User and Group are required only if using any of the SSH modes to store
# group root # the keys in /root/.ssh directory (or any user with homedir and shell)
# env.NetMode Telnet # Connection mode, can be 'Telnet' or 'SSHPass' or 'SSHKey'
# env.Port 23 # Port of the Telnet service configured in AirOS F web interface
# env.User foobar # Username to log in
# env.Pass raboof # Password to log in
# env.PingAddr 192.168.2.3 # An IP address to ping, typically the other wireless device or a gateway
# env.PingName slave.wlan # Friendly name of the pinged device, to display on the ping graph
#
# [ubiquiti_airos_slave.wlan]
# user root
# group root
# env.NetMode SSHPass
# env.Port 22
# env.User foobar
# env.Pass raboof
# env.PingAddr 192.168.2.2
# env.PingName master.wlan
#
# 4. In /etc/munin/munin.conf add them as new virtual nodes:
#
# [master.wlan]
# address 127.0.0.1
#
# [slave.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.
#
# To use the script with public keys authentication and no password, set env.NetMode SSHkey, and
# create a pair of keys using command 'sudo ssh-keygen -t rsa'. This will generate in /root/.ssh
# directory two files, id_rsa and id_rsa.pub. Upload id_rsa.pub to your Ubiquiti device using
# Services > SSH Server > Authorized Keys window. Try to log in to the device by command line
# first ('sudo ssh foobar@slave.wlan'), to save the RSA key fingerprint in the root account.
#
# Plugin based on my similar one for AirMax devices:
# http://community.ubnt.com/t5/airOS-Software-Configuration/Updated-airOS-plugin-for-Munin-monitoring/td-p/469169
#
# Tested & working with munin v.2.0.14 and AirOS F v1.1.2.
# Created in 2013 by robi
# v0.3 - added SSH support and saved some memory, thanks to NVX@UbiquitiNetworksCommunity
# v0.2 - cleared up stuff related to naming and added ping graphs from munin-node
# v0.1 - initial version, based on ubiquiti_airos_ v0.7.
