Using Sun Management Center Administrative Domains |
A Sun Management Center administrative domain is an arbitrary collection of resources that can include a complete campus, individual buildings, hosts, networks, subnets, links, and so on. The organization of an administrative domain collection is in a hierarchy.
Note - In this document, "administrative domain" refers to a Sun Management Center administrative domain, and should not be confused with other uses of the term "domain" related to other Sun products or documentation.
This chapter describes the following topics:
Sun Management Center software can monitor a multitude of hosts. To enable you to perform your monitoring tasks in an efficient manner, Sun Management Center software organizes hosts into groups. The biggest (highest level) grouping is a administrative domain. An administrative domain is an arbitrary grouping of hosts, subnets, networks, buildings, and so on.
You can create one or multiple administrative domains, each with an unique name. Each administrative domain consists of one or more members, arranged in a hierarchy. For example, you may decide that an administrative domain consists of all the hosts in one building. Or, you may decide that an administrative domain consists of all the hosts in a campus.
Note - Spend some time planning how you want to organize your hosts into different administrative domains.
Decide if you need additional groups below the administrative domain to organize your hosts. For example, if there are several hundred hosts, it is impractical to place your hosts individually in one administrative domain.
You may decide to break the administrative domain into a set of smaller groups; for example, campuses. The Headquarters administrative domain might consist of several campus locations (FIGURE 1-4).
Each of these campus locations may be broken into smaller groups; for example, buildings. Similarly, each building may be broken into smaller groups; for example, networks, subnets, and groups. Finally, each group comprises individual hosts.
In this particular example, the hierarchical order, from highest level to lowest level, is administrative domain, campus, building, network, subnet, group, and individual host. For detailed information on creating administrative domains, see "To Create Administrative Domains".
When starting the software for the first time, a dialog is displayed that prompts you to set a Sun Management Center home administrative domain. The home domain is the administrative domain that is displayed whenever the console is started.
During installation, a default administrative domain (named after your server host) is automatically created for you.
Proceed with one of the following:
