CDEF convert Bits into MBPS

abdulcc · Post by **abdulcc** » Fri Jul 14, 2006 7:09 am

Hello All

I have a cdef defined cdef=CURRENT_DATA_SOURCE,1000000,/ such as to convert bits/second into megabits /second

I cannot get it to display on my graph and I would really apreciate if someone could show me how to do it!!!

Thanks,

Post your resulting graph syntax using debug under graph management.

RRDTool Says:

OK

I guess my cdef troubles comes from where it is highlithed in red

Doesnt someone have a template that will convert bits per second into megabits per second Thanks. This is the template I am using.

Interface - Traffic (bits/sec, Total Bandwidth)

It's more a querkynees in the interface. The cdefbc likely does not work right?

Hi all,

trying to use the following to convert to megabits/sec (Mbps):

Code: Select all

cdef=CURRENT_DATA_SOURCE,8,*,1048576,/

I'm ending up with graphs like this:

Why is it showing 50m ? It should be showing like 1Mbps or .253 Mbps or 8.34Mbps.

TIA!

Hi

50m means 0.050

What GPRINT type are you using in your graph template ?

Hi. I am using the 'Normal' GPRINT. Something I fooled around with is the 'unit-exponent' value for the graph. I changed it to 0 and now it shows on the Y-axis, 0.1.

Is that the correct location to change this?

I changed the GPRINT to 'Exact Numbers' and everything now shows 0 where in the graph above, it shows 457.29m and 554.13u etc.

Thanks for your help.
