Systems and methods for monitoring power in power distribution systems are provided. In one aspect, a system for monitoring power includes a power monitoring device that measures a value of at least one characteristic of power provided to a branch of a power distribution system. The power monitoring device includes an output that provides the value measured. The system further includes a controller having an input to receive the value measured and an output that couples to a first device powered by the branch to send a maximum power signal to the first device to command the first device to operate at a percentage of maximum power.

What is claimed is: 1. A method of controlling operation of a computer comprising: receiving a power control input signal within the computer; determining a predetermined percentage of maximum power from the input signal; and controlling the computer to operate at substantially the predetermined percentage of maximum power by controlling at least one processor in the computer to perform an additional task adapted to cause the computer to operate at the predetermined percentage of maximum power. 2. The method of claim 1, wherein the predetermined percentage is 100 percent. 3. The method of claim 2, wherein controlling the computer to operate at substantially the predetermined percentage of maximum power includes controlling subsystems within the computer to operate at a maximum power level. 4. The method of claim 3, further comprising: controlling the computer to return to an original power state. 5. The method of claim 1, wherein the computer is configured to perform an idle task having a priority level, and wherein the additional task is assigned a priority level higher than the priority level of the idle task. 6. The method of claim 5, wherein the processor is configured to perform other tasks, each of which has a priority level, and wherein the priority level of the additional task is lower than the priority level of each of the other tasks. 7. The method of claim 1, further comprising: controlling the computer to return to an original power state. 8. The method of claim 1, wherein the processor is configured to perform other tasks, each of which has a priority level, and wherein the priority level of the additional task is lower than the priority level of each of the other tasks. 9. A computer system comprising: an input to receive a power control input signal; and a control module configured to: determine a predetermined percentage of maximum power from the power control input signal; and control the computer system to operate at substantially the predetermined percentage of maximum power, wherein control the computer system includes controlling at least one processor in the computer system to perform an additional task adapted to cause the computer system to operate at the predetermined percentage of maximum power. 10. The computer system of claim 9, wherein the predetermined percentage is 100 percent. 11. The computer system of claim 10, wherein the control module is configured to control subsystems within the computer system to operate at a maximum power level. 12. The computer system of claim 11, wherein the control module is further configured to control the computer system to return to an original power state. 13. The computer system of claim 9, wherein the computer system is configured to perform an idle task having a priority level, and wherein the additional task is assigned a priority level higher than the priority level of the idle task. 14. The computer system of claim 13, wherein the processor is configured to perform other tasks, each of which has a priority level, and wherein the priority level of the additional task is lower than the priority level of each of the other tasks. 15. The computer system of claim 9, wherein the processor is configured to perform other tasks, each of which has a priority level, and wherein the priority level of the additional task is lower than the priority level of each of the other tasks. 16. A method for monitoring and controlling a power distribution system for providing power to a plurality of computer devices, the method comprising: controlling a first computer device to operate at a first controlled power level; detecting a first value of power provided to the first computer device; controlling a second computer device to operate at a second controlled power level; detecting a second value of power provided to the second computer device; and based on the first value and the second value, controlling at least one of the first computer device and the second computer device to operate at a third controlled power level. 17. The method of claim 16, wherein the third controlled power level is less than the first controlled power level and less than the second controlled power level. 18. The method of claim 16, wherein the first controlled power level is a maximum power level of the first computer device and the second controlled power level is a maximum power level of the second computer device. 19. The method of claim 16, wherein the power distribution system includes an uninterruptible power supply, and wherein the method further includes: detecting when the uninterruptible power supply is operating in battery mode; and controlling at least one of the plurality of devices to operate in a reduced power mode upon detection of the battery mode. 20. The method of claim 16, further comprising: controlling a third computer device to operate at a fourth controlled power level; detecting a third value of power provided to the third computer device; controlling a fourth computer device to operate at a fifth controlled power level; and based on the third value and the fourth value, controlling one of the third computer device and the fourth computer device to operate at a fifth controlled power level.
