The faulty conditions are detected during an execution of a program; the program includes at least one function. The method includes initializing Application Program Interfaces (APIs) across the at least one function. After this, calls to the APIs used within a namespace of the program are intercepted. The interception is performed by the at least one function through extended method classes. Thereafter, the usage of the resources for the at least function intercepting the APIs is checked against a corresponding predetermined threshold limit. Once the usage of the resources is checked, context of the usage of the resources is identified based on a predefined knowledge. Subsequently, the occurrence of the faulty conditions is determined based on the identification. ## Claims ### Claim 1 A method for preemptive detection of occurrence of one or more faulty conditions based on usage of one or more resources executed by one or more computing devices, the one or more faulty conditions are detected during an execution of a program, the program comprising at least one function, the method comprising: a. initializing Application Program Interfaces (APIs) across the at least one function defined in the program;
