[mrtg-developers] How to add values of two OID in MRTG

[Gayan S. Amarasiri]

Hi,

I need to add two parameters and show it in graph using MRTG. For example let say the OID 1.3.4.5.26.626.26.26.0 gives Mathematics marks and the OID 1.3.4.5.26.626.26.27.0 gives the Science marks. I need to draw a graph for the total marks which is the addition of the vales of the above OIDs. How to do these type of stuff? Appreciate your help.

Thanks & BR,
Gayan
