=head1 NAME
|
|
|
|
mpdstats_ - Munin plugin to monitor a MPD database
|
|
|
|
=head1 DEPENDENCIES
|
|
|
|
This plugin uses netcat(1) to communicate with the MPD daemon.
|
|
|
|
Tip: To see if it is already set up correctly, just run this plugin
|
|
with the parameter "autoconf". If you get a "yes", everything should
|
|
work like a charm already.
|
|
|
|
=head1 INSTALLATION
|
|
|
|
This wildcard plugin should be symlinked using one of these names:
|
|
mpdstats_artists, mpdstats_albums, mpdstats_songs
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
No configuration should be required if run on the same server as
|
|
MPD. If the plugin is run from remote or in a non-default configuration,
|
|
please use the environment variables 'mpd_host' and 'mpd_port' to connect.
|
|
|
|
Also, if your netcat(1) binary is anywhere else than /bin/nc please define
|
|
it using the 'netcat' environment variable.
|
|
|
|
=head2 CONFIGURATION EXAMPLE
|
|
|
|
[mpdstats_*]
|
|
env.mpd_host 192.168.0.43
|
|
env.mpd_port 6606
|
|
env.netcat /usr/local/bin/nc
