=head1 NAME
=head1 APPLICABLE SYSTEMS
=head1 CONFIGURATION
You have to setup ssh with public key authentication for this plugin
SNMP is only used for getting the hostname
[snmp_$host_netapp_diskbusy]
env.ssh /usr/bin/ssh (default)
env.sshuser munin (default)
env.sshopts -i /home/munin/.ssh/id_rsa -o UserKnownHostsFile=/home/munin/.ssh/known_hosts (no default)
env.spares 2 (no default)
Number of spares is only used for total diskusage.
=head1 INTERPRETATION
This plugin only prints the disk busy status at check time. There is no
average calculated, but it still gives a goood overview if all disk are
used equally or you have got a single hot disk.
