Installs Nagios3 from packages.

Includes nova client used to get a list of IPs to monitor. Any found IPs are added to the Nagios "generic-host" group which should provide basic ping and ssh monitoring.

Access via http interface at http:///nagios3. Sets the default web user name as nagiosadmin with a password of nagiosadmin.

Options to set the web password and parse nova list output for initial ip list can be provided via heat. For example:

nagios3:
    adm_web_passwd: nagiosadmin
    nova_host_ip: 192.0.2.1
    nova_os_password: unset
    nova_os_username: admin
    nova_os_tenant_name: admin
    initial_network_split_key: ctlplane
