I have been looking at this for far too long. I am convinced that what I am doing is right, but usually, when I am convinced of that, I am doing something stupid and just can't see it. Creating a rrd with: rrdtool create db/req.rrd --start 1295054280 --step 30 DS:centos:COUNTER:60:U:URunning the application, which is adding data thus: rrdtool update /home/philip/Monitor/db/req.rrd 1295054880:ULooking at the contents: $ rrdtool fetch db/req.rrd LAST -s -300 -e NLooks ok. Now plot a graph: rrdtool graph hour/req.png -a PNG --title="Production Directory Server Operations Requested" \and we get this:  Note graph starting at ~33.6 million, rather than 0.033. Although this is a COUNTER, there is nothing there that looks like a reset. There is even a U inserted as the first value, just to be safe. What an I doing wrong??? $ rrdtool --version RRDtool 1.4.4 Copyright 1997-2010 by Tobias Oetiker <[email protected]> Compiled Sep 20 2010 11:28:29 |
