Exact field meaning of /proc/stat

  • 772

everyone

I need to know the exact meaning of every field in /proc/stat file. I read man proc and it only lists several common fields in various architecture and I find in Ubuntu, it includes several other fields in cpu row.

the below is output in my system and cpu rows contain up to 10 columns while the manual only gives 8 column definitions. Furthermore, I can't match the order of columns between my output and the manual.

cpu  606833 402 200307 3888129 69330 0 2702 0 18958 0
cpu0 305810 176 95771 1937157 42348 0 2581 0 9824 0
cpu1 301023 226 104535 1950972 26982 0 121 0 9134 0
