[mrtg] Graphing disk iowait on Debian using mrtg and routers2

[Mike Bordignon]

Hello,

I'm trying to graph iowait on Debian but having trouble finding 
examples. Is it best to use an
iostat bash script or the SNMP counter (.1.3.6.1.4.1.2021.11.54.0)?

The SNMP counter seems to be an ever increasing value. I thought it 
might be the number
of seconds the CPU has waited for, but I'm not sure how to use this value?

Any help much appreciated.



cheers
Mike
