2 Group Management

Groups are administrative structures that organize assets so that you can locate an asset quickly or perform operations on all assets of the same type. Groups can contain any number of assets, and assets can be members of more than one group. This chapter describes how to use groups to manage your assets.

Smart Groups

Oracle Enterprise Manager Ops Center creates groups of major asset types automatically. Within these Smart Groups, a subgroup is created for each type of asset that Oracle Enterprise Manager Ops Center is managing. Use Smart Groups to locate and view assets of a specific type. You can also act on Smart Groups, such as changing monitoring thresholds and updating discovery credentials.

Oracle Enterprise Manager Ops Center creates these Smart Groups:

User-Defined Groups

User-defined groups can contain any type of asset and can be organized by any criteria. You can configure rules for user-defined groups that automatically add assets with specific characteristics to the group.

Viewing Smart Groups

Smart groups are automatically generated groups that organize your assets by type.

To View a Smart Group

  1. Select the Assets in the Navigation pane.

  2. Select a Smart Group from the dropdown list at the top of the pane.

  3. (Optional) Select a subgroup in the Navigation pane. The smart group is displayed.

Viewing Group Data

Each group can list all the assets in the group and can display data about their assets. Chassis and hardware groups display power usage information, and operating system groups display CPU, network, memory, and system load information.

To View Group Data

  1. Expand Assets in the Navigation pane.

  2. Select All User-Defined Groups.

  3. Select a group. The group dashboard is displayed. This includes:

    • A group summary that shows the group's name, description, tags, location, and number of members.

    • A membership graph showing the group's assets, any child groups, and any parent groups.

    • A status summary showing the problems of the assets within the group.

    • An asset summary showing basic data about the assets within the group.

Starting Jobs on a Group

You can perform operations on all the assets in a homogeneous group by choosing the group as the target for asset-specific actions. For example, you can provision an OS on many systems simultaneously.

The selected action is applied only to compatible assets. For example, if you select the Locator Light On action for a group of servers, the job targets only servers that have locator lights.

To Start a Job on a Group

  1. Select All User-Defined Groups from the Assets list in the Navigation Pane.

  2. Select the group. Asset-specific actions are displayed in the Actions pane.

  3. Click an action. The action is applied to all compatible assets within the group.

Creating a Group

You can organize your assets into groups to aid in management and inventory.

To Create a Group

  1. Expand All Assets in the Assets section of the Navigation pane.

    • Description (optional) – This is a description of the group that is displayed in the group's dashboard.

    • Group Location – A group's position within the tree. You can create a group at the top level (root) or as a child of an existing group.

    • Configure Group Rules – Use this option to specify the membership rules. Any assets that match the rules are added to the group.

    • Configure Subgroups – Uset this option to specify any existing group as a child of this group.

    • Asset Type – Select the asset type that uses the rule.

    • Attribute – Select an attribute to be considered by the rule. For example, if you select Name, the rule compares the asset's name to a given value. You can add additional attributes to a rule using the Add Attribute icon.

    • Condition – Select a condition for the rule. For example, if you select Contains for the Name attribute, the rule includes assets if their name contains a given value.

    • Value – Enter a value to be used by the rule. For example, if you select Name as an Attribute, Contains as a condition, and Pod3 as a value, any asset of the specified type with Pod3 in its name is added to the group.

  5. If you selected Configure Subgroups, the Configure Subgroups page is displayed. Drag one or more groups from the Available Groups list to the Selected Groups list, then click Next.

  6. If you selected Preview Group Before Creation, the Preview Group page is displayed. Review the list of assets and subgroups that will be added to the new group, then click Next.

If you change or remove the rules of an existing group, assets added by those rules are removed if they do not match the new rules. However, assets that were added manuall are not removed.
