The system configuration dump (if --quiet is not used) is followed by statistics. The first row of the statistics labels the content of each column (below). The second row of statistics is the system summary line. The system summary line has a '-' in the columns for the Package, Core, and CPU. The contents of the system summary line depends on the type of column. Columns that count items (eg. IRQ) show the sum across all CPUs in the system. Columns that show a percentage show the average across all CPUs in the system. Columns that dump raw MSR values simply show 0 in the summary. After the system summary row, each row describes a specific Package/Core/CPU. Note that if the --cpu parameter is used to limit which specific CPUs are displayed, turbostat will still collect statistics for all CPUs in the system and will still show the system summary for all CPUs in the system.

This example also shows the use of the --hide option to skip columns that are not wanted. This example also shows the use of the --show option to show only the desired columns.
Note that cpu4 in this example is 99.99% busy, while the other CPUs are all under 1% busy.
Notice that cpu4's HT sibling is cpu0, which is under 1% busy, but can get into CPU%c1 only,
because its cpu4's activity on shared hardware keeps it from entering a deeper C-state.
