  • Patent number: 10802947
    Abstract: A computer-implanted method for creating a filtered digital entry includes generating, via a processor implementing a trace generation engine, a trace indicative of successful transactions and erroneous transactions. The processor instantiates a plurality of buffers in a buffer pool each configured to record a trace function boundary. The processor then analyzes each buffer in the buffer pool based on the trace function boundary to evaluate whether each function entry in the trace contains an erroneous transaction. If the processor determines that a function entry contains an erroneous transaction, the processor sets an output flag in a call stack map associated with that function. The processor then generates a filtered digital entry based on the call stack map. The filtered digital entry includes only erroneous transaction data from the trace.
