US 11,144,352 B2 · Correlation of thread intensity and heap usage to identify heap-hoarding stack traces

Abstract

Embodiments identify heap-hoarding stack traces to optimize memory efficiency. Some embodiments can determine a length of time when heap usage by processes exceeds a threshold. Some embodiments may then determine heap information of the processes for the length of time, where the heap information comprise heap usage information for each interval in the length of time. Next, some embodiments can determine thread information of the one or more processes for the length of time, wherein determining the thread information comprises determining classes of threads and wherein the thread information comprises, for each of the classes of threads, thread intensity information for each of the intervals. Some embodiments may then correlate the heap information with the thread information to identify code that correspond to the heap usage exceeding the threshold. Some embodiments may then initiate actions associated with the code.

Dependent claims

A computer-implemented method, the method being performed by one or more computer systems and comprising:

determining heap information of one or more processes during a length of time, the heap information comprising heap usage information and a smoothed heap usage seasonal factor for a season of each of a plurality of intervals in the length of time;
determining thread information of the one or more processes during the length of time, wherein the thread information comprises a smoothed thread intensity seasonal factor for a season of each of the plurality of intervals in the length of time;
correlating the heap information with the thread information to identify one or more lines of code of the one or more processes that correspond to the heap usage exceeding a threshold;
and
responsive to identifying the one or more lines of code, initiating one or more actions associated with the one or more lines of code.

2 more elements

A system comprising:

one or more processors;
and
a memory accessible to the one or more processors, the memory storing one or more instructions that, upon execution by the one or more processors, causes the one or more processors to:
determine heap information of one or more processes during a length of time, the heap information comprising heap usage information and a smoothed heap usage seasonal factor for a season of each of a plurality of intervals in the length of time;
determine thread information of the one or more processes during the length of time, wherein the thread information comprises a smoothed thread intensity seasonal factor for a season of each of the plurality of intervals in the length of time;
correlate the heap information with the thread information to identify one or more lines of code of the one or more processes that correspond to the heap usage exceeding a threshold;
and
responsive to identifying the one or more lines of code, initiate one or more actions associated with the one or more lines of code.
