Discovery Manager Concepts

The Discovery Manager can find hosts, routers, networks, and subnets as explained in Overview of IP Addressing. The Discovery Manager also discovers objects where a Sun Management Center agent is configured to a different server context as described in Sun Management Center Server Context and Security.

The Discovery Manager can also find and group topology objects. These objects can be related either to a single hardware platform or to a group of cooperating hardware platforms. This discovery and grouping feature enables convenient management of the related objects. This technique is described in the add-on supplement for those machine architectures that have this grouping requirement.

---

Note –

For additional information, refer to your platform supplement. The supplement contains important platform-specific information about discovering objects.

---

You can create one or more discover requests. Each request runs as a separate process and adds the discovered objects to the administrative domain. The Discovery feature is supported only for administrative domains and not for any subordinate groups. You can add requests only for an administrative domain.

You can also schedule requests to look periodically for new hosts.

---

Note –

Every discover request is assigned a Request ID. This ID is a unique Sun Management Center internal identifier of the request. The Request IDs might not be in sequential order. The Request ID displays in the Request Details portion of the Discover Requests Window.
