I am having issues with horrible performance on my WAN with several sites. My provider tells me that they are seeing my router recieve from the WAN at 100% utilization for about 5-10 seconds every 40-50 seconds. My MRTG and Netflow don't tell me much because the sample time for Netflow and MRTG normalizes it out since it isn't 100% recieve from the WAN all the time. Any way I can get better visibility into what is doing this?
Thanks
