The formula to calculate the CPU ready percent (R) is:
\[ R = \left( \frac{T_r}{T_t} \right) \times 100 \]
Where:
CPU ready percent is a metric used to measure the percentage of time that a virtual machine’s CPU is ready to run but is waiting for physical CPU resources to become available. This metric is crucial in virtualized environments where multiple virtual machines share the same physical CPU resources. A high CPU ready percent indicates that the virtual machine is experiencing CPU contention, which can lead to performance degradation. Monitoring and optimizing CPU ready percent can help ensure that virtual machines run efficiently and maintain optimal performance.
Let's assume the following values:
Using the formula to calculate the CPU ready percent (R):
\[ R = \left( \frac{T_r}{T_t} \right) \times 100 = \left( \frac{500}{10000} \right) \times 100 = 5\% \]
The CPU Ready Percent (R) is 5%.
