Hi Everyone,<div> I'm new to rrdtool and this users list. I have a task in my hand for which i would like to get your valuable suggestions. I have a data pipeline to monitor. I will be storing the sent, received_good values for every minutes in an rrd for each server. I would like to plot a Standard Deviation Graph for this system (also an alerting system) which compares this hour's data (sent and received data will be considered seperately for monitoring) with historic data for the same hour (like prevoius day same hour, previous week same day same hour, previous month same day same hour, prev year same day same hour). As of my understanding rrd averages the old data. So what would be the best strategy for me here ? Also like to know from you the use cases of Standard deviation in rrd. </div>
