=head1 NAME
hpacu - Munin plugin to monitor HP Array Controllers
=head1 CONFIGURATION
The plugin needs to be able to execute /usr/sbin/hpacucli, which requires
root permissions. The following configuration is needed:
[hpacu]
user=root
=head1 INTERPRETATION
The graph will show information about number of controllers,
logical drives and physical drives that are ok or degraded.

hpfan - Munin plugin to monitor HP server fans
=head1 CONFIGURATION
The plugin needs to be able to execute /sbin/hplog, which requires
root permissions. The following configuration is needed:
[hpfan]
user=root
=head1 INTERPRETATION
The graph will show information about how many fans are ok and how
many are degratded.
It does not, currently, show the speed of the fans.
