After some frustration I noticed that the rrdtool lastupdate returns the last value that was updated to the specific rrd file. I know may people are saying "yea duh." Never the less it took a while for me to understand that in a rrd with a data source of type DERIVE this didn't mean the last value that was stored in the rrd, it was the last value given to the rrd. <div>
<br></div><div>Is there a way to easily get the last value that was stored in the rrd? or do I just need to fish it out of the data returned from a rrdtool fetch?</div><div><br></div><div>Also, is there an explanation anywhere for the information returned from an rrdtool info query?</div>
