[mrtg] Re: Multiple OID

[Sawyer, David]

Try adding a few brackets around your target to confirm the order of
calculation...

Target[Agg-Traffic]: 
   ((3:community at router1.mycompany.com * 100) / 64000) + 
   ((2:community at router2.mycompany.com * 100) / 128000)

Take a look at my site and click the 'MRTG help' link, it gives a few
examples.

Why multiply it by 100 then divide by 64000?
Why not just divide by 640?

Target[Agg-Traffic]: 
   (3:community at router1.mycompany.com / 640) + 
   (2:community at router2.mycompany.com / 1280)

Hi,

Does RRD supports multiple oid per target?  i want to get an aggregate
utilization of my 2 (1Mb & 522Kb) Wan links terminated at 2 different
routers.  So far, i have no success in graphing what i want.  im using
mrtg-2.9.17 with rrdtool and router.cgi for graphing.  attached is my config
for those who care to help.  thanks.
