[mrtg] Re: Adding up data from more than one interface

[Paul C. Williamson]

You should be able to.

Just do something like this...

Target[target_name]: OID1&OID2:community at device1 +  
OID1&OID2:community at device2 + ....

I think the OIDs (OID1 & OID2) can be the same if you only 
want one number for the result.

hi there,

I'm trying to produce some sort of aggregate graph of snmp data from a
bunch of load-balanced servers, such that the graph is the sum of
information from more than one source.

I've had a look at the mrtg configuration file format, and it appears that
this isn't possible, but I may be wrong.  If this IS possible, then can
anyone give me some tips for this?  If not, I'll just have to hack it, but
I figured I'd ask before I start becoming familiar with the source :-)

Cheers,

Giles
