Embodiments of the present invention include a method, apparatus, system, and/or computer program for monitoring energy consumption in a network and producing a display grid that provides a visual depiction of network device power consumption at any given time. The method includes, in one example, receiving a request for a power level schedule for a network device. The request may include a time period or date range over which the power level schedule should be produced. The method may also include retrieving Cron job strings associated with the network device, and parsing the Cron job strings to determine transitions from one power level to another and times for the transitions of the power level of the network device. The method further includes building a visual grid that depicts the power level schedule for the network device during each hour of the time period, based on the determined transitions.
