All,

Carrying on from the above work that I've been doing, I've been considering
how we should allow the user to define a dynamic remote host. As mentioned above
I believe that the user should be forced into providing a set of templates.
A template essentially defines a type of dynamic remote host that can join the
Blue monitoring network. By defining this template, the user essentially tells
Blue that when it sees a host of type 'x' request the join the network, it should
apply the templated monitoring configuration.

Obviously one of the aims is to keep the definition of any objects as closely
tied to the current format as possible. So I am proposing the following syntax
for the definition of dynamic templates:

define dynamic_template{

 remote_template_name      db_server
 uses_host                 name_of_defined_host_template_in_my_hosts.cfg
 runs_services             comma_seperated_list_of_services_from_services.cfg
 contact_name              contact_from_contacts.cfg
 contact_group             contact_group_from_contactgroups.cfg
 joins_hostgroup           hostgroup_from_hostsgroups.cfg
}

So in essence I see a host of type 'db_server' attempt to join the network.
The dynamic registrar knows what host configuration to apply, what service
configuration to apply etc. It then writes this configuration into the dynamic.cfg
and issues the command into the external command file for blue to read in the
configuration. Obviously the hostname and host address fields of the host definition
are changed by the dynamic registrar to that of the host attempting to register.

Any thoughts?

Rob
