[mrtg] Question about multiple targets

[Alex Ball]

Hello,

I have a need to get two OIDs from two separate hosts and graph them
together.  I also need to do an operation (* -1) on both results,
suggestions?

I have tried:

Target[name]: <oid>:public@<ipA>&<oid>:public@<ipB> * -1


Target[name]: (<oid>:public@<ipA> * -1) & (<oid>:public@<ipB> * -1)


Target[name]: <oid>:public@<ipA> + <oid>:public@<ipB> * -1

Thanks,

-Alex
