=head1 NAME
ipmi_ - Plugin to monitor temperature or fan speed using IPMI
=head1 CONFIGURATION
=head2 ENVIRONMENT VARIABLES
This plugin does not use environment variables
=head2 WILDCARD PLUGIN
This plugin should be linked as ipmi_temp or ipmi_fans, and will show
either temperatures or fan speeds based on its link name.
=head1 NOTE
WARNING: Munin has a 10 second default timeout on plugins. On some
hosts ipmitool takes longer than that to probe all your hardware. In
this case this plugin us unusable.
