Re: [CentOS] vmstat and loadavg disagree about system load

Hi John,

Followed line is quoted from “man vmstat”, it means r+b=running process + uninterruptible sleep process. So, what’s the definition of system load, doesn’t it include running process and process in uninterruptible sleep. Which part is wrong? Please explicitly denote.

I could care less what man pages say, I'm saying THATS NOT HOW IT WORKS. Linux has *ALWAYS* worked this way. Load Average is measuring something completely different than your 'r' and 'b' in vmstat. Presumably, there are far more processes in 'interruptable sleep' than 'uninterruptable sleep', and vmstat doesn't seem to count these.
