Computer application error root cause diagnostic tool

A computer system for determining a root cause of an error associated with a computer application, the system comprising:

• a processor;
• and
• computer memory having computer-readable instructions embodied thereon, that, when executed by the processor, perform operations comprising:
• detect an error during an operation of a subject computer application on the computer system;
• determine a first telemetry data set comprising telemetry data of the computer system for a time frame that includes an occurrence of the error;
• accessing a plurality of fault profiles, each fault profile in the plurality of fault profiles including at least an indication of a fault that is different than the faults indicated by other fault profiles of the plurality;
• for each fault profile in the plurality of fault profiles, perform a comparison operation of the first telemetry data set and the fault profile, thereby performing a plurality of comparison operations;
• and
• based on the plurality of comparison operations, determining a first relevant fault profile from the plurality of fault profiles;
• based on the first relevant fault profile, determining a root cause of the error;
• and
• provide an indication of the root cause of the error.

A computer-implemented method for determining a root cause of an error associated with a subject computer application, the method comprising:

• operating the subject computer application on a first computer system according to a first condition of operation, the subject computer application operating within a first time frame that is a first-condition session;
• determining a first-condition telemetry data set by monitoring the first computer system during the first-condition session;
• operating the subject computer application on the first computer system according to a second condition of operation, the subject computer application operating within a second time frame that is a second-condition session;
• during the second-condition session, causing a fault associated with the operation of the subject computer application during the second-condition session;
• determining a second-condition telemetry data set by monitoring the first computer system during the second-condition session;
• based on a comparison of the first-condition telemetry data set and the second-condition telemetry data set, programmatically determining a data aspect included in the second-condition telemetry data set that is not included in the first-condition telemetry data set;
• generating a fault profile that is a data structure that comprises at least an indication of the fault and the data aspect included in the second-condition telemetry data set;
• and
• based on an indication that an error is detected in connection with the subject computer application, providing the fault profile.
