1. A method for real time job resource monitoring in a computing system, comprising: analyzing input for a job, the job provided to the computing system for a job execution with one or more application instances on the computing system, and the job execution consuming processing resources of the computing system; estimating total resource requirements of the job execution on the computing system based on the analysis of the input; monitoring usage of the processing resources throughout the job execution on the computing system, including repeatedly verifying future resource availability for the job during the job execution by: measuring cumulative resource consumption for the job and available resource levels in the computing system; estimating future resource requirements of the execution of the job based on the total resource requirements of the job and cumulative resource consumption for the job; comparing the future resource requirements of the execution of the job with the available resource levels in the computing system; and predicting a resource deficiency if the future resource requirements exceed the available resource levels in the computing system; and implementing one or more actions to prevent failure of the job execution on the computing system responsive to prediction of the resource deficiency.
