The Data Volume allows you to view at a glance your account's data usage volume by category, collector, source name, and hosts. The app uses predefined searches and a Dashboard that provide visibility into your environment for real-time analysis of overall usage.
Before you can use the Data Volume app, an administrator must first enable the feature. For more information, see Enable and Manage the Data Volume Index.
Once the Data Volume Index is enabled, volume data is not back filled to any time before the feature was enabled. Data is only provided from the time the feature is enabled forward.
