A computing device includes at least one processor and a machine-readable storage medium storing instructions. The instructions may be executable by the hardware processor to, in response to a detection of an application event during execution of an application, read a plurality of entries included in a call stack at a time of the application event. The instructions are also executable to determine a classification identifier for the application event using the plurality of entries included in the call stack, and store information about the application event in a database entry associated with the classification identifier.
