the paging-related columns (re, pi, po, fr, sr, cy, in, sy)
Actually, vmstat data is in 5 sections: kthr - threads
r - running
b - blocked (by something).
memory
avm - addressable virtual memory
free - free frames in system memory
page
fi/fo (pages in/out of file system space - to/from file memory)
pi/po (pages in/out of paging space - to/from working memory)
fr/sr: frames freed/scanned (searched)
cy (not in -w output) clock cycles used by page strealer
faults
in - hardware interuptts
sy - system calls
cs - context switches
cpu
us/sy - user/system time BUSY
id/wa - IDLE nothing to do/waiting for io to finish before switch to busy
What I suggest you use is one of the two following commands - perhaps 5 second intervals as a start, and move up as you get more insight.
Note the argument -w for wide, and -I for file activity

How do you reset the values that vmstat displays?
Vmstat displays a running average from the last the system was restarted on the first line, how do you reset these values without restarting the system? (Solaris 8) (3 Replies)
When I exeute vmstat (e.g. vmstat 30 2),
in some machines I get some wierd result as the first line.
like: -117% or 208% for CPU idle percentage.
But the second line is alright.
Could someone explain this please.
Thanks !

Hi AIX Expert,
