I am collecting total accumulation data from a water meter. The data collected is the last value during different time periods. 10s, 30 minutes and 1 day. The meter resets every day at midnight.<div><br></div><div>I create daily, weekly and monthly graphs. They all resemble a sawtooth shape with a straight line down to zero at midnight.</div>
<div><br></div><div>The monthly graph is where I am having issues. I was hoping that it would show daily total, the last value just before it reset. However is just shows a more compressed sawtooth.</div><div><br></div>
<div>
I next set the step to be 86400s, or 1 day. This created a graph that is very close to what I want except that the end of the 1 day step is not at midnight. </div><div><br></div><div>DEF:ds=/var/www/client/rrds/reg_UID_105.rrd:data_source:LAST:step=86400:start=end-4w:end=0\:00"</div>
<div><br></div><div>Is there a way to force the beginning or end of the step?</div><div><br></div><div>Does it have something to do with the start time of the rrd itself?</div><div><br></div><div>Should I be going about this in a different manner?</div>
