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
cpu r b w swpd free buff cache si so bi bo in cs us sy id 10 0 0 4828 12240 74940 36412 0 0 0 0 0 0

0 0 100and another one from a redhat 3 :

I put the output from a redhat as 4 (update 2) :
procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 96 44128 217952 3371248 0 0 1 17 0 0 1 0 98 0 0 0 96 44064 217952 3371248 0 0 0 12 2080 55 0 0 100 0 0 0 96 44064 217952 3371248 0 0 0 24 2076 48 0 0 100 0 0 0 96 44128 217952 3371248 0 0 0 12 2080 54 0 0 100 0 0 0 96 54240 217952 3371248 0 0 0 17 2073 54 0 0 100 0
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)
Define some host vmstat hash column translation
