=head1 NAME
asterisk_codecs - Plugin to monitor number of active channels by codec
used
=head1 ABOUT
This plugin uses the asterisk manager API to fetch data.
=head1 CONFIGURATION
The following configuration parameters are used by this plugin
[asterisk_codecs]
env.host - hostname to connect to
env.port - port number to connect to
env.username - username used for authentication
env.secret - secret used for authentication
env.codecs - List of codecs (names)
env.codecsx - List of codecs (hexadecimal values)
The values of codecs and codecx must match each other. Asterisk
returns a hexadecimal value representing the codec used, and the same
list entry is used from "codecs" and "codecsx".
The "username" and "secret" parameters are mandatory, and have no
defaults.
=head2 DEFAULT CONFIGURATION
[asterisk_codecs]
env.host 127.0.0.1
env.port 5038
env.codecs gsm ulaw alaw
env.codecsx 0x2 0x4 0x8
