Hi all,<br> I know the subject of spikes is a fairly popular discussion. We have an issue here where our equipment will become busy for short periods of time (usually a couple of minutes). We poll for interface information on 1 minute intervals which results in several NaNs. Once the device is again responsive to SNMP, we usually get a value that is equal to all the traffic that has passed during the NaN interval. This results in a spike in the graph. During high usage times, this spike will not occur as it exceeds the maximum defined value in the RRA, but during low usage we do get the spike. After researching it seems that its always the value that directly follows one or more NaNs that is the issue. Is there a way within the graph function to ignore any CF value that follows a NaN as unreliable as far as graphing goes (which should get rid of my spike)? It seems that would also take care of devices which reboot?
<br><br>Thanks<br>Chris<br>
