vmstat reporting incorrect cpu usage
I've noticed if i run vmstat with no params when rebuilding the kernel i get this right: # vmstat procs memory page disk faults cpu r b w avmfre flt re pi po fr sr ad0 in sy cs us sy id 2 1 0 294156 44596 313 0 0 0 296 1 0 82 85 225 14 8 78 # But, if i run it like this # vmstat -c 2 procs memory page disk faults cpu r b w avmfre flt re pi po fr sr ad0 in sy cs us sy id 1 1 0 299580 38204 313 0 0 0 296 1 0 82 85 225 14 8 78 1 1 0 294996 42876 886 0 0 0 2061 0 3 1364 2231 81 19 0 # The second result shows what top does, but the first one seems to be completely wrong... # vmstat -c 6 procs memory page disk faults cpu r b w avmfre flt re pi po fr sr ad0 in sy cs us sy id 1 1 0 300136 36196 313 0 0 0 296 1 0 82 85 225 14 8 78 1 1 0 301040 35312 230 0 0 0 9 0 0 2193 489 2156 87 13 0 1 1 0 296720 39644 1234 0 0 0 2326 0 5 2190 1530 2185 70 30 0 1 1 0 297092 39228 1435 0 0 0 1336 0 3 2200 1562 2188 75 25 0 1 1 0 298488 37844 1573 0 0 0 1229 0 4 2206 1592 2191 69 31 0 1 1 0 299372 36908 316 0 0 0 123 0 96 2301 618 2442 86 14 0 # Only the first one seems to do it though...
