[mrtg] MRTG and blank cpu graphs...........please help

[Steve Shipway]

If you use RRDtool mode for MRTG instead of native mode, then it can happily
log decimals so 0.4% will display correctly.

 

If you tell MRTG the same OID twice and don't give the noo option, then the
graph will show the same line twice.  So you are seeing the blue line and
the green area, but both are the same OID so the same CPU.  They represent
the same thing.

Thanks a lot for your help...I sorted it out actually based on a suggestion
given by one of the members in the forum....The reason being the load on the
router wasnt much..It was like 0.4% which MRTG was rounding of to zero....So
i actually managed to load the router and could see the results.....Its also
that we need to wait for three successive polls before we can see the
results


  


However i have got a small question.As we know that MRTG needs two variables
to graph the data but the cisco 2811 series router which i am using has only
one cpu....So i used the same OID for representing both the variables which
is like 


 


1.3.6.1.4.1.9.2.1.58.0&1.3.6.1.4.1.9.2.1.58.0......


  


But i didnt use the switch options[xxxx]:noo to hide the second variable and
MRTG was giving two graphs........How is this possible the router has only
cpu and i should be seeing only one graph that is the blue one but
suprisingly MRTG is drawing the green graph as well.What data could this
green graph represent......Is it just graphing some random data or what??
