Generating, aggregating, and querying virtualization service execution metrics using in-memory processing

A computer storage medium storing computer-useable instructions that, when used by a computing device, cause the computing device to perform operations comprising:

• executing a command configuring a computer system emulator on the computing device by causing a virtualization service provider running in a virtualization stack to execute a plurality of virtualization service operations configuring the computing device on behalf of a virtualization service client of the computer system emulator;
• and
• aggregating execution metrics for the plurality of virtualization service operations over a current interval using in-memory processing, and to push the aggregated execution metrics to a structure in memory storing historical aggregated execution metrics.

A method comprising:

• executing a command configuring a computer system emulator by causing a virtualization service provider running in a virtualization stack on the host computer to execute a plurality of virtualization service operations configuring the host computer on behalf of a virtualization service client of the computer system emulator;
• and
• aggregating execution metrics for the plurality of virtualization service operations over a current interval using in-memory processing and pushing the aggregated execution metrics to a structure in memory storing historical aggregated execution metrics.
