[mrtg-developers] Re: PATCH: Custom table support

[Simon Leinen]

Phil,

your patch looks like a very useful generalization of an important
feature in MRTG.

What I don't understand is why you even need the `TableName' - it
should be sufficient that the `Header' and `RetrieveField' have the
same index structure, right?

In some cases there may not even be a common table, e.g. you may want
to refer to ifDescr (from ifTable) and retrieve ifHCInOctets (from
ifXTable).
