Does anyone know if you can divide one oid by another in MRTG? I manage
Nortel routers and have determined that Nortel calculates cpu utilization
by dividing cpu used by cpu max.  Cpu used and cpu max both have a
corresponding oid.  Unfortunately, the cpu max value changes over time as
it is reported in centiseconds.  I could set a value for MaxBytes that
would always be greater than Cpu max but would prefer to divide one oid by
the other as this would produce the most accurate value. Thanks for your
