Data Domain System Details

Detail reports are related to a specific enterprise object, such as a backup job. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. They are not available in search results.

Explore your data center using IT Analytics customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.

Use the Reports tab to examine the IT Analytics catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. The main report is located here:
