You can do this if you have the Routers2 frontend.

First, on the one returning Kilobytes, use

Factor[]: 1024

To convert the value to bytes.  This way we're all talking the same units.

Next, you can define a userdefined summary graph over the two Targets with 
total enabled:

routers.cgi*Graph[target1]: mysummary total
routers.cgi*Graph[target2]: mysummary total
routers.cgi*Desc[mysummary]: My Summary Graph
routers.cgi*ShortDesc[mysummary]: Both

Hope this helps,

Steve

Subject: [mrtg] summarizing different types of data

hi,

I have 2 network devices. one of them is a 10 Gbps Foundry switch which which 
returns its bandwidth usage in Gauge32. The other returns the same value using 
Integers. The Gauge32 is also providing its value in kilobytes, vs the other 
one's bytes.
I need to summarize these two.
I am not sure how to go about it. the 10 Gbps device's config looks something 
like this:

LoadMIBS: (path specified, mib is 
correct)MIB-OID-FOUNDRY-SN-SWITCH-GROUP-MIB.mib
WorkDir: (specified, irrelevant)

Target[sum-net]: 
.1.3.6.1.4.1.1991.1.1.3.3.5.1.54.22&.1.3.6.1.4.1.1991.1.1.3.3.5.1.55.22:[EMAIL 
PROTECTED]:::::2 * 128
Options[sum-net]: Gauge, nopercent
Title[sum-net]:
MaxBytes[sum-net]: 100000000000
PageTop[sum-net]: <H1>Net Total Traffic</H1>

The non-10 Gig thing's config is something like this:

WorkDir: (specified, irrelevant)

Target[sum-net1]: 1:[EMAIL PROTECTED]:::::2
Title[sum-net1]: device1
MaxBytes[sum-net1]: 10000000000
PageTop[sum-net1]: <H1>Net1 Total Traffic</H1>


Both these work perfectly. However, how do I add them up? clearly 
.1.3.6.1.4.1.1991.1.1.3.3.5.1.54.22&.1.3.6.1.4.1.1991.1.1.3.3.5.1.55.22:[EMAIL 
PROTECTED]:::::2 * 128 + 1:[EMAIL PROTECTED]:::::2 in this case will not work.

Any insight would be most appreciated.

thank you
Gabor
