Hi All,
I am using MRTG application and need inputs on the MRTG graph behaviour.
The router config file has certain OID’s which on polling may or may not return a result. Now in case there is no result, I am manually setting the value to 0 in the rrd file. This causes spikes of very high value in the graph when the traffic is stopped.
To avoid this I removed those lines of code where I was manually setting the value to 0 so that "NaN" gets written in the rrd files. This resulted in hanging graphs (graph values starting from middle instead of starting from 0).
I also tried setting the option “unknaszero” in the router config file. This option was plotting the correct continuous graphs but the graph legend/label was still showing the value 0.
Can anyone suggest a solution for this if you have come across this kind of behaviour?
Thanks in advance,
Nisha
