Xilinx U280
The Xilinx xrt driver allows to measure power using a standalone command line tool. The specific tool invocation and output format depends on the xrt version (module xilinx/xrt and configuration constraint xilinx_u280_xrt...).
Usage example and sample output for xrt 2.12, after selecting the first card. During this example, the card is idle and configured with the validation bitstream.

Bittware 520N
The Bittware driver allows to measure power using a standalone command line application tool that queries the board power via the i2c bus. It's available on all FPGA nodes with Bittware 520N cards (irrespective of the constraint).
