Fresh is both RAM and disk. To get the RAM cache ratio it is traffic_top also.
The colors are kinda arbitrary. I "borrowed" the idea from dstat. For percentages: 100 - 90 -> red 90 - 80 -> yellow 50 - 80 -> blue 0 - 50 -> geen For numbers: Trillion -> red Billion -> red Million -> yellow Thousand -> cyan (should be blue) <= 1000 -> green There is a bug in the timing information. -Bryan > On Mar 12, 2019, at 12:16 PM, Jason Yang <[email protected]> wrote: > > Hi Bryan and community, > Thank you for your reply!
