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.

=head1 NAME

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.
