Monitoring ADSL lines with MRTG

Hi,

My network has two ADSL 512Kbps lines and I am doing per-destination load balancing with CEF enabled.

I am getting a few link utilization graphs from MRTG server for both the dialer interfaces and ATM physical interfaces.

I would like to know if I should take the graphs plotted for Dialer interfaces or for ATM interfaces when it comes to correctly figuring out my network's internet utilization.

Thanks,

Vasanth

Re: Monitoring ADSL lines with MRTG

MRTG is polling the device at certain intervals using SNMP.The polled values are real-time data and not the average. Depending on the time you are polling, you may sometimes get a higher value and sometime you get a lower value, but not the average. Even if you average all the polled data, the result will not be the real average.
