-#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:

+#Tested & working with munin v.2.0.14 and AirOS v5.5.6.
+#Created in 2013 by robi
+# 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
