#
# Multigraph munin plugin to monitor Ubiquiti AirOS 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_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, add them to your /etc/hosts file, like below:
#    192.168.2.2	apo.wlan
#    192.168.2.3	cli.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_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]
#    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 or SSH service configured in AirOS 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 cli.wlan	# Friendly name of the pinged device, to display on the ping graph
#
#    [ubiquiti_airos_cli.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 apo.wlan
#
# 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.
#
# 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@cli.wlan'), to save the RSA key fingerprint in the root account.
#
# 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 v5.5.6.
# Created in 2013 by robi
#  v0.9 - added SSH support and saved some memory, thanks to NVX@UbiquitiNetworksCommunity
#  v0.8 - cleared up stuff related to naming and added ping graphs from munin-node
#  v0.7 - added critical thresholds to some graphs, and some descriptions below some of them
#  v0.6 - added wlan errors by type graph - useful to detect interferences on the same frequency; added CPU usage graph
#  v0.5 - added ping graph - ping times from the AirOS device to a configured address; other fixes
#  v0.4 - corrected memory size unit calculation and display, fixed query bug, fancier graphs for memory and link speed
#  v0.3 - added undefined values handling in case of connection timeout, corrected linefeed character handling
#  v0.2 - combined all the separate pugins into one multigraph plugin, a couple of charts separated
#  v0.1 - initial version, separate plugin for each graph, packaged 11 different plugins
