org.rhq.core.domain.drift.DriftDefinitionTemplate

A drift definition template (or drift template for short) is a drift definition that applies at the type level like an alert template. Drift templates can be defined in plugin descriptors as a way to provide suggested and/or common definitions for users wanting to monitor resources of that type. Users can also create templates from admin section of the UI where templates can be managed. Template can be created from existing definitions.

A pinned drift template is pinned to a specific snapshot and applies at the type level. A pinned template can be created from an existing snapshot that belongs to a particular resource. Definitions created from a pinned template are pinned as well and use the template's snapshot as their snapshots.

When a pinned template is deleted, all definitions created from said template are deleted as well. With an unpinned template however, the definitions can outlive the template.
