[mrtg] Re: Total Traffic

[Glenn Forbes Fleming Larratt]

Two ways, of which I'm aware.

1. Configure a Target[] that is your aggregate, and include every item you're
polling in an arithmetic expression.

Pro: intermediate-level MRTG configuration task

Con: hard to maintain if your list of stuff changes with any freqency
Con: don't know how well it'll scale
Con: poll every monitored point twice, so your data may not concisely match

2. Write a script that you use to poll every target, and cache the value so
you can do mathematical tricks with the resulting data.

Pro: poll every monitored point once, data will match (i.e. A + B = (A+B) )

Con: more difficult task
Con: more CPU intensive on your MRTG host
Con: still doesn't scale very well
Con: only a little easier if your list changes with any frequency.
