in vCloud director under our only provider VDC its showing the CPU "Total" metric as being 120Ghz despite it being nearer 180Ghz. Where does it pull this information from as were trying to report on current usage and need this corrected
can you please upload the screenshot? just trying to understand the context.
Retrieval of both current and historical metrics is available through the vCloud API. The current metrics are directly retrieved from the VMware vCenter Server™ database with the Performance Manager API. The historical metrics are collected every 5 minutes (with 20 seconds granularity) by a StatsFeeder process running on the cells and are pushed to persistent storage—Cassandra NoSQL database cluster with KairosDB database schema and API. KairosDB provides an API endpoint for vCloud cells to store and retrieve data.
