Complex devices, software systems, and/or networks may comprise one or more subsystems that perform periodic tasks. A first task may be assigned a first execution frequency and a second task may be assigned a second execution frequency that is not an alias of the first execution frequency (e.g., assignment of execution intervals that are non-overlapping harmonics of each other, such as non-repeating frequencies). A first resource utilization by the first task may be distinguished from a second resource utilization of the second task based upon the first resource utilization corresponding to resource utilization (e.g., network usage, processor usage, power consumption, user access, etc.) associated with the first execution frequency and the second resource utilization corresponding to resource utilization associated with the second execution frequency. Thus, resource utilization of individual tasks of various subsystems and/or networks may be determined.
