Abstract
A hardware based utilization metering device, and a corresponding method are used in a computer system having one or more central processor units (CPUs) to provide a measure of CPU utilization. The device includes a state indicator coupled to a CPU. The state indicator receives an indication when the CPU is in a first state, which may be a busy state. A counter coupled to the state indicator and coupled to a system clock, receives a measure of system time from the system clock and receives data related to the indication when the CPU is in the first state, and generates a counter value indicative of time the CPU is in the first state. A data usage provider coupled to the counter maintains a non-volatile value of the counter value.
