Light-emitting diodes (LEDs) are ubiquitous in electronic hardware, where they serve to indicate device state and/or provide debug information, e.g., during product development. If indicator LEDs are retained in production hardware, equipment owners incur substantial capital and operating costs. This disclosure describes the virtual LED (vLED), a technique that leverages connectivity through an on-board controller such as a baseboard management controller (BMC) to transmit real-time information equivalent to the state of the physical indicator-LED to a log file communicated through a browser or other tool. The vLED provides the equivalent functionalities as a physical LED while costing nearly nothing and enabling the remote access of equipment, the capture of rare events, the analysis of error logs by models, the adding of additional indication-features after general availability (GA) of the equipment, etc.
