Abstract
Techniques for categorizing exceptions and logs are described. For example, exception data of an exception that occurred on a machine is accessed. The exception data includes a stack trace of the exception. A determination is made that the exception is unique based on the stack track of the exception. Responsive to the determination that the exception is unique, the exception is categorized, by a machine including a memory and at least one processor, into one or more categories based on the stack trace of the exception.
Claims18
A computer-implemented method comprising:
- accessing exception data of an exception that occurred on a machine, the exception data including a stack trace of the exception;
- determining that the exception is unique based on the stack trace of the exception, the determining that the exception is unique including:
- removing dynamic data from the stack trace of the exception to result in a stripped stack trace of the exception,
- applying a hash function to the stripped stack trace to calculate a particular primary hash code that uniquely identifies the stripped stack trace of the exception,
- accessing one or more primary hash codes stored in a record of a database,
- comparing the particular primary hash code against the one or more primary hash codes, and
- determining that the particular primary hash code is not included in the one or more primary hash codes;
- responsive to the determining that the exception is unique, performing a first categorizing, using one or more hardware processors, of the exception into one or more categories based on the stack trace of the exception;
- removing additional data from the stripped stack trace of the exception to result in a twice-stripped stack trace of the exception;
- applying the hash function to the twice-stripped stack trace to calculate a particular secondary hash code associated with the exception;
- and
- performing a second categorizing of the exception into the one or more categories based on the particular secondary hash code associated with the exception.
