=head1 NAME
squeezebox_ - plugin to monitor a SqueezeCenter and associated
players.
=head1 APPLICABLE SYSTEMS
Probably any system running SqueezeCenter. Change the host to allow
for remote monitoring.
=head1 CONFIGURATION
No configuration should be required if run on the same server as
SqueezeCenter. If the plugin is run from another unit or in a
non-default configuration, please use the environment variables
'squeezebox_host' and 'squeezebox_port' to connect. Also, if your
nc(1) binary is not called "nc", or not the one in $PATH, please define it
in the plugin's environment file (/etc/munin/squeezebox or similar).
Sample follows:
[squeezebox_*]
env.squeezebox_host 192.168.100.10
env.squeezebox_port 9095
env.netcat /usr/local/bin/nc
=head1 INTERPRETATION
The "volume" graphs only graphs the player's volume, not the amplifier
or whatever the player is connected to.
=head1 MAGIC MARKERS
