Problems solved by technology

Performance issues may be experienced during execution of software applications.
Typically, users (including administrators) may perceive that the software application (while being executed) is not providing an expected throughput performance, even though occasional situations arise where a software application exceeds such expectations.
Performance bottlenecks refer to those aspects of execution of software applications that are potentially causing the corresponding performance issues.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE DISCLOSURE

1. Definitions

[0017]Super-sequence: A sequence of modules indicating the chain of invocations during execution of a software application. Formally stated, a super-sequence represented by M1 through Mq (wherein q is any arbitrary integer) indicates the module Mi has invoked module Mi+1, wherein i is an integer within a range of 1 to (i−1).

[0018]Sub-sequence: Part of a super-sequence, again indicating the chain of invocations.

[0019]Length of a sequence: The number of modules in the sequence. The term ‘long sub-sequence’ means that the length is a large number.

[0020]Long sub-sequence of invocations of modules occurring frequently: A sub-sequence which can be inferred to have co

Abstract

An aspect of the present disclosure aids investigation of performance bottlenecks occurring during execution of software applications. In an embodiment, a set of long sub-sequences of invocations of modules occurring frequently during execution of a software application are identified. Such identified sub-sequences are notified to a user (e.g., administrator) for examination of any performance bottlenecks during execution of the software application. According to another aspect, a log is formed containing super-sequences of invocation of modules formed during execution of the software application. The log is examined to identify a respective frequency of occurrence of multiple sub-sequences of invocations, wherein the set of long sub-sequences are identified based on the identified frequencies and respective length (i.e., number of modules in the sequence) of each of the plurality of sub-sequences of invocations.
