I have some Proliant with iLO boards here, and they are working quite

I use place used up for my calculation, so that 20% free space is 80%
used space, so I write:

define service{
        use                             frontends
        host_name                       foo
        service_description             Disk L:

well, you get the idea... warning, when 20% free, critical, when 5%

Use the iLO-boards, when available, and put them in a separate VLAN,
which is dedicated only for management and monitoring purposes.
I am using SNMPv2 without fear, because the iLO-boards and the nagios
station are in a VLAN with private IP, which is not accessible from
(You also should spend a thought of configuring a firewall whether on
the machine, or elsewhere, that is blocking Port 161 on all interfaces
which are not used. Second best way is a dedicated management Ethernet
interface in that box..
