Hi,
I see strange vmstat graphs on these 2 Oses : Redhat AS 2.1 (ia32) and
Redhat AS 3 (ia32 and ia64). It seems that some columns were inverted
or shifted, here is the output of vmstat on a redhat 2.1 :
procs memory swap io system

It seems graphs don't care about the idle column. I put the output
from a redhat as 4 (update 2) :
procs -----------memory---------- ---swap-- -----io---- --system--
----cpu----

On this particular os, vmstat graphs are ok. On a Debian 3.1 system,
graphs look good too.
So, what can I do ? Is there a file to modify, a package to install ?
Remove Redhat and install a Debian...

Hi,
in the past I had the same problem. This is how I have adapt the
vmstat-larrd.pl:
It makes the correlation between the columns of vmstat output depending
on the OS / kernel version (2.4 / 2.6)
