Generating and attributing unique identifiers representing performance issues within a call stack

Various embodiments discussed herein enable unique identifiers or hash values to be generated that uniquely identify performance issues and associated call stack units, which may be attributed to a user or team of users. A performance issue for a currently running process can be detected. A particular location within a call stack of the process indicating where the performance issue was detected can be determined. A quantity of call stack frames within the particular location that account for a threshold proportion of the performance issue can be determined. A hash value that uniquely identifies the performance issued can be generated based at least in part on the particular location and the quantity of call stack frames within the particular location that account for the threshold proportion of the performance issue.
