Re: vmstat and loadavg disagree about system load

[Mingfei Hua <mfhua@xxxxxxxxxxxx>]

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.

>         b: The number of processes in uninterruptible sleep.



Regards,

Mingfei

'should' according to what ?



Linux has *NEVER* worked that way.
