Hello Darren, Thanks for your reply
In my case I use mrtg to read eth interface counters to plot traffic interface. Based on your 2 options and if I m not mistaken : 1. Repeat the last known value : if both values are the same, traffic plotted is zero, and if the next pooling is ok traffic displayed is higher than the reality ( twice if traffic is constant ) 2. Log as zero : Then when next pooling is ok, traffic displayed is unrealistic ( huge spike ) Ideally when pooling failed , the traffic calculation should be done with the last valid pooling and the new one BUT over 10 mn ( if pooling is done each 5 mn ) Is there a way to this ? Hoping to be clear ...

The default behaviour in this case is to repeat the last value. If this is not desirable, then the 'unknaszero' option may be used, which will cause MRTG to log all unknown values as zero. So essentially, there are two options: 1. Repeat the last known value 2. Log as zero See http://oss.oetiker.ch/mrtg/doc/mrtg-reference.en.html cheers, Darren _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
