Systems and methods for benchmark based cross platform service demand prediction

A system comprising:

• one or more processors;
• and
• one or more internal data storage devices operatively coupled to the one or more processors for storing:
• an input file creator configured to:
• receive, from an application profiler, pre-defined method calls made by an application under test, wherein the pre-defined method calls are lower level method calls corresponding to a technology stack used by the application under test and wherein the pre-defined method calls are selected based on a number of times a method is invoked during the execution of the application and an amount of time a method takes excluding sub-calls made by the method;
• receive, from the application profiler, data flow sequences between client tier, application tier and database tier of the application under test;
• analyze one or more transactions of the application under test, received from a network packet analyzer, wherein analyzing the one or more transactions comprises characterizing send and receive network calls between the application under test and one or more external services including a database and a client accessing the application under test to identify operations impacting central processing unit (CPU) utilization;
• and
• generate an input file for each of the one or more transactions based on output from the application profiler and the network packet analyzer, wherein the input file includes a transaction name, a number of web requests made by the transaction, data flow within the transaction and an amount of bytes transferred between each pair of the tiers, a type of SQL statement, the method calls and corresponding invocations;
• a skeletal performance mimicking benchmark (PMB) Repository comprising skeletal benchmarks corresponding to one or more technology stacks usable by one more applications including the application under test;
• and
• a Performance Mimicking Benchmark (PMB) generator configured to:
• select, from the skeletal performance mimicking benchmark (PMB) Repository, a skeletal benchmark corresponding to the technology stack used by the application under test;
• and
• generate a performance mimicking benchmark (PMB) corresponding to the application under test based on the skeletal benchmark and the input file.

A computer program product comprising a non-transitory computer readable medium having program instructions embodied therein for:

• profiling an application under test, by an application profiler, to obtain pre-defined method calls made by the application under test, wherein the pre-defined method calls are lower level method calls corresponding to a technology stack used by the application under test and wherein the pre-defined method calls are selected based on a number of times a method is invoked during the execution of the application and an amount of time a method takes excluding sub-calls made by the method;
• capturing, by the application profiler, data flow sequences between client tier, application tier and database tier of the application under test;
• analyzing, by a network packet analyzer, one or more transactions of the application under test, wherein analyzing the one or more transactions comprises characterizing send and receive network calls between the application under test and one or more external services including a database and a client accessing the application under test to identify operations impacting central processing unit (CPU) utilization;
• generating, by an input file creator, an input file for each of the one or more transactions based on output from the application profiler and the network packet analyzer, wherein the input file includes a transaction name, a number of web requests made by the transaction, data flow within the transaction and an amount of bytes transferred between each pair of the tiers, a type of SQL statement, the method calls and corresponding invocations;
• selecting, from a skeletal performance mimicking benchmark (PMB) Repository, a skeletal benchmark corresponding to the technology stack used by the application under test;
• and
• generating, by a Performance Mimicking Benchmark (PMB) generator, a performance mimicking benchmark (PMB) corresponding to the application under test based on the skeletal benchmark and the input file.
