[mrtg] Arithmetic on multiple OIDs

[Jean-Eric Cuendet]

Hi,
I'm configuring MRTG at our site, and need to do some arithmetic on OIDs
values. I saw in MRTG/configuration reference that it's possible to do it,
but don't know exactly how. The doc is sparse on the subject...

So, I'd like to add User+System+Nice CPU usage into one graph and having
CPU/Idle on the second graph. How to do that?

I need cpu.user.0+cpu.system.0+cpu.nice.0 & cpu.idle.0
Any idea?

Thanks
