I have a lot of data collected in rrd files. Does anyone know of a script, or part of the rrd toolset that will show 'spikes'.
Basically I would like to give it a window specified by start time and end time. Then maybe a threshold above the average for that would be considered a spike. Then I would like the tool to print out the time stamps for those spikes and the values.
I know I could make some graphs and look at them, but that's not really what I am after with this. If nobody has a solution, I will probably whip something up in Perl, so any suggestions are also welcome.
