Data Object Reference
What is a data object?
- Data objects are domain-specific and not necessarily general purpose.
- Data objects expose their attributes as either dimensions or measures.
Dimension and Measure Attributes
- Dimension attributes are typically used to explore various breakdowns of data, by using them in aggregation queries.
- Measure attributes are typically sourced from observability telemetry reporting numeric instrumentation values from some data source (for instance Oracle internal V$ views.)
The common query pattern encouraged and enabled by explorers is to aggregate measures over dimensions. These are referred to as analytic type queries.
Ops Insights provides the following data objects:
For Exadata Database Service on Dedicated Infrastructure targets, only Exadata Disk Hourly and Exadata Disk Daily data objects are supported.
Top Processes data object will not have data for Enterprise Manager or Cloud Database nodes and/or hosts.

| AWR_PDB_* Views | The AWR_PDB views show the local Automatic Workload Repository (AWR) data present on a CDB root or a PDB.
The AWR_PDB views can be interchanged with the DBA_HIST views. For example, you can use the AWR_PDB_ACTIVE_SESS_HISTORY view for retrieving the AWR data about the active session history at the PDB level for all the sources registered to the Hub, which is equivalent to the DBA_HIST_ACTIVE_SESS_HISTORY. For detailed per-view list of DBA_HIST* views see: DBA_HIST* Views. Used by: AWR Hub Explorer |
