To fix it:

sudo chown username /dev/bpf*

I'm working in FreeBSD so your mileage may very a little on Linux.

Extract the check_openmanage-3.1.1.tar.gz
tar -zxvf check_openmanage-3.1.1.tar.gz

Place check_openmanage in /usr/local/libexec/nagios
cd check_openmanage-3.1.1
cp check_openmanage /usr/local/libexec/nagios

Might have to make it executable as well
chmod +x /usr/local/libexec/nagios/check_openmanage

Define your OpenManage command in commands.cfg
# 'check_openmanage' command definition
define command{
command_name check_openmanage
command_line $USER1$/check_openmanage -s -H $HOSTADDRESS$ -i -C public
}

Define your service in your server.cfg
define service{
use local-service ; Name of service template to use
host_name servername
service_description Perc RAID
check_command check_openmanage!
}

You should end up with notices that look like this

For Monitoring ESX/ESXi I had to find another route. The VMware toolkit is made for linux, and searching around it didn't look promising on FreeBSD. Luckily for me someone else had already figured this out. See Ubergeek Technical Howtos' for details.
