=head1 NAME
freeipmi - Multigraph-plugin to monitor sensors using FreeIPMI
=head1 CONFIGURATION
When used to monitor the local host, plugin config should define user root for direct ipmi access:
[freeipmi]
user root
=head2 ENVIRONMENT VARIABLES
When used to monitor a foreign host, this plugins use the variables
IPMI_USERNAME and IPMI_PASSWORD to log in on the remote system.
=head2 WILDCARD PLUGIN
When used for the local host, the plugin should be linked as
non-wildcard plugin, i.e., 'freeipmi', whereas when used to monitor a
foreign host it should be, e.g., 'freeipmi_192.168.0.253'.
=head1 DEPENDENCIES
The plugin requires FreeIPMI 1.1.5 or later to fetch the information.
Limits set on thresholds are available when using FreeIPMI 1.2.0 or
later.
