[rrd-users] rrdfetch ?

[Warrick FitzGerald]

Hi All,

I know someone is going to kick me for this, but why when I follow the
example tutorial on the rrdtool.org site

see:
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/tutorial/rrdtutorial.html

I create the db as explained
rrdtool create test.rrd --start 920804400 DS:speed:COUNTER:600:U:U
RRA:AVERAGE:0.5:1:24 RRA:AVERAGE:0.5:6:10

I insert some test date as explained
rrdtool update test.rrd 920804700:12345 920805000:12357 920805300:12363
rrdtool update test.rrd 920805600:12363 920805900:12363 920806200:12373
rrdtool update test.rrd 920806500:12383 920806800:12393 920807100:12399
rrdtool update test.rrd 920807400:12405 920807700:12411 920808000:12415
rrdtool update test.rrd 920808300:12420 920808600:12422 920808900:12423

However, when I try and fetch the data, I get the following :

 920804400: nan
 920804700: nan
 920805000: 4.0000000000e-02
 920805300: 2.0000000000e-02
 920805600: 0.0000000000e+00
 920805900: 0.0000000000e+00
 920806200: 3.3333333333e-02
 920806500: 3.3333333333e-02
 920806800: 3.3333333333e-02
 920807100: 2.0000000000e-02
 920807400: 2.0000000000e-02
 920807700: 2.0000000000e-02
 920808000: 1.3333333333e-02
 920808300: 1.6666666667e-02
 920808600: 6.6666666667e-03
 920808900: 3.3333333333e-03
 920809200: nan

1. Why is my timeslot  920804700 = nan ?
2. Why do all the numbers look weird (ie. I inserted an integer and got some
strange output ??)

Thanks
Warrick
