Software request-filtering predictive technique based on resource usage probabilities

A computer program product for filtering requests to be forwarded to a runtime environment, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor in a filtering apparatus to cause the processor to:

• intercept a runtime request before the runtime request enters the runtime environment, wherein the runtime environment comprises a plurality of resources and wherein one or more of the resources in the plurality of resources may be utilized to execute the runtime request;
• determine one or more execution paths that may be traversed within the runtime environment, wherein each execution path in the one or more execution paths comprises at least one difference in resources utilized;
• assign a probability of traversal to each execution path in the one or more execution paths;
• identify at least one execution path of the one or more execution paths that references a stressed resource of the runtime environment;
• based on the probabilities assigned to the at least one execution path, determine whether or not to block the runtime request from being sent to the runtime environment;
• in response to determining that the probability assigned to the at least one execution path exceeds a configured threshold, block the runtime request from being sent to the runtime environment;
• and
• in response to determining that the probability assigned to the at least one execution path does not exceed the configured threshold, send the runtime request to the runtime environment.
