Detection, diagnosis, and mitigation of software faults

A processor configured to:

• measure at least one first runtime metric of software executing on the processor;
• construct, in a operating space, a geometric enclosure based on the at least one measured first runtime metric;
• measure at least one second runtime metric of the software;
• place the at least one second runtime metric in the operating space;
• determine that the software is in normal operating state when the at least one second runtime metric is located within or on a perimeter of the geometric enclosure;
• and
• determine that the software is in an abnormal operating state when the at least one second runtime metric is located outside of the geometric enclosure.

A computer-readable storage medium that is not a propagating signal, the computer-readable storage medium comprising executable instruction for detecting a software fault, the executable instructions, when executed by a processor, cause the processor to effectuate operations comprising:

• measuring at least one first runtime metric of software executing on a processor;
• constructing, in a operating space, a geometric enclosure based on the at least one measured first runtime metric;
• measuring at least one second runtime metric of the software;
• placing the at least one second runtime metric in the operating space;
• determining that the software is in normal operating state when the at least one second runtime metric is located within or on a perimeter of the geometric enclosure;
• and
• determining that the software is in an abnormal operating state when the at least one second runtime metric is located outside of the geometric enclosure.
