A computer implemented method for extended monitoring of a database includes establishing a data virtualization communications connection between a first and a second datacenter that is a copy of the first datacenter. Requests for monitoring information corresponding to the first datacenter are made by accessing its system views. Requests for monitoring information corresponding to the second datacenter are made by generating virtual tables on the first datacenter to provide the system views of the second datacenter to the first datacenter and accessing the virtual tables. The monitoring information corresponding to the first datacenter is grouped into a first schema on the first datacenter and the monitoring information corresponding to the second datacenter is grouped into a second schema, separate from the first schema. A union view is generated by combining the monitoring data associated with the two datacenters. Related apparatus, systems, techniques and articles are also described.
