Hi there, Despite setting all my datapoints as DERIVE instead of COUNTER and also an RRD Min of 0, I still get a graph where it will spike periodically, similar to the picture found in http://forums.zenoss.com/viewtopic.php?t=5145.
This datasource is a command that I run via ssh on the remote machine, which outputs Nagios-style statistics. The command counts the number of occurrences of the string "error" in a logfile. When the logfile gets rolled, however, the command returns a count of 0, which is when this spike occurs. I read the docs and followed the instructions for avoiding this statistical anomaly (DERIVE + RRD Min=0) but it still occurs. I also tried setting an RRD Max of 100000 (as the spike values are always > 1M), but the datapoints still get graphed, causing my threshold alert to often be set off inadvertently. I guess a spinoff question is whether the RRDMax applies to the stat returned or the processed data point (e.g. the derivative value instead of the original value) though this doesn't really matter in this case anyway. Any help would be much appreciated - thanks!
