    • The CPU Utilization Percentage section shows CPU processes as a percentage of CPU activity:
      • System CPU—the time spent executing system kernel code
      • User CPU—the time spent executing application code
      • Nice CPU—the time spent executing processes that have had their processing priority altered

    • The Memory Utilization Percentage section shows memory usage as a percentage of available real and swap (or disk) memory:
      • Real Memory—shows the percentage of physical memory used.

        Real memory usage is calculated by taking total free memory and cached memory into account. The real memory usage percentage is calculated as follows:

        Total Real Memory Usage Percentage = (Physical-(Free + Cached))/(Physical)

      • Swap Memory—shows the percentage of swap or disk memory used.

        Swap memory usage is calculated by taking total physical memory, free memory, cached memory, and buffer memory into account. The memory usage percentage is calculated as follows:

        Total Swap Memory Usage Percentage = (SwapTotal-SwapFree)/(SwapTotal)
