Douglas, As you didn't give specific times in your sample data its a bit difficult to see how they match to you fetch. However, if you are using COUNTER, then you would expect the numbers in the RRD to be ([EMAIL PROTECTED] - [EMAIL PROTECTED])/(timeX - timeX-1). i.e. what is the rate per second

Can you tell me why my data looks so funny (wrong) ?? I'm trying to push some data with: rrdtool update myrouter.rrd N:267821925:20944716 rrdtool update myrouter.rrd N:267821925:20948633 . blah . blah . Note that the numbers are pretty big. Now when I fetch look what I get? rrdtool fetch /tmp/gg/myrouter.rrd AVERAGE --start -60min input output 979136700: NaN NaN 979137000: NaN NaN 979137300: 8.8828260870e+02 2.9260869565e+01 979137600: 1.3062894893e+03 5.6148930297e+01 979137900: 7.0555488630e+03 1.6408999114e+02 979138200: 4.6983517132e+03 9.9709547886e+01 979138500: 1.5006727604e+04 1.1251607986e+02 979138800: 3.8324676923e+03 7.0591682692e+01 979139100: 3.8570030476e+03 7.1427047619e+01 979139400: 5.3599769524e+03 9.5546285714e+01 979139700: NaN NaN 979140000: NaN NaN 979140300: NaN NaN 979140600: NaN NaN These numbers are not even close to what I got before? Am I missing something? I can't convert these back to anything close to the original numbers. Here is a little script I wrote to see if I could at least see some patterns. This basically uses time and a random number. The graphs for the random number look random but the time is (for the most part) a horizontal line?? Heres the script: while true do etime=`perl -e 'print time, "\n" '` echo "using epoc as :$etime:" rnum=`perl -e 'print rand(1000), "\n" '` echo "using rnum as :$rnum:" echo "rrdtool update db1.rrd N:$etime:$rnum" rrdtool update db1.rrd N:$etime:$rnum echo "Fetching" rrdtool fetch db1.rrd AVERAGE --start -5min echo "Sleeping for 5" sleep 5 echo; echo; echo; done Here is the output: using epoc as :979145754: using rnum as :125.8544921875: rrdtool update db1.rrd N:979145754:125.8544921875 Fetching epoch rnum 979145430: 1.0066666667e+00 5.3293185764e+01 979145460: 1.0000000000e+00 7.6229926215e+01 979145490: 1.0000000000e+00 9.4349568685e+01 979145520: 1.0000000000e+00 8.0090196398e+01 979145550: 1.0000000000e+00 6.4478895399e+01 979145580: 1.0000000000e+00 9.1949055990e+01 979145610: 1.0000000000e+00 1.0993591309e+02 979145640: 1.0000000000e+00 7.5236002604e+01 979145670: 1.0000000000e+00 8.6906941732e+01 979145700: 9.9444444444e-01 1.0479109022e+02 979145730: 9.9222222222e-01 1.0253394233e+02 979145760: NaN NaN Sleeping for 5 using epoc as :979145759: using rnum as :996.2158203125: rrdtool update db1.rrd N:979145759:996.2158203125 Fetching epoch rnum 979145430: 1.0066666667e+00 5.3293185764e+01 979145460: 1.0000000000e+00 7.6229926215e+01 979145490: 1.0000000000e+00 9.4349568685e+01 979145520: 1.0000000000e+00 8.0090196398e+01 979145550: 1.0000000000e+00 6.4478895399e+01 979145580: 1.0000000000e+00 9.1949055990e+01 979145610: 1.0000000000e+00 1.0993591309e+02 979145640: 1.0000000000e+00 7.5236002604e+01 979145670: 1.0000000000e+00 8.6906941732e+01 979145700: 9.9444444444e-01 1.0479109022e+02 979145730: 9.9222222222e-01 1.0253394233e+02 979145760: NaN NaN Sleeping for 5 Thanks for any help, Douglas -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi ********************************************************************** This correspondence is for the named person's use only.
