Abstract: Embodiments of the present invention disclose system for workload analyzing and optimization. The system includes one or more processors which are configured to capture, in real time, electrical signature data of one or more sub-systems running on a main system. The electrical signature is captured by one or more sensors coupled to a power controller. The captured electrical signature data into at least time domain or frequency domain. A volume of a workload of the one or more sub-systems is determined based on the converted data and a first threshold data. A type of the workload is determined based on the converted data and a second threshold data. A report is generated based on the determined volume and the type of workload.
