[rrd-users] Re: Tutorial problem

[Schockaert, Rudy]

Hi Ronald,

I'm studying the tutorials on a Windows 2000 Professional and have similar
results. However, I don't see where the problem lies. It is true that the
format of the result is different than what is shown in tutorial, but the
values are the same and the graphs are correct.
I guess the diference is there because the tutorial was made with an older
version of RRD.

Great job from Tobias for RRD and from Alex for the tutorial.

Rudy

Subject: [rrd-users] Tutorial problem



Howdy all,

I've been reading the RRD Tutorial, and I'm experiencing some problems with 
the examples.  I enter the commands exactally as listed, but my results are 
_far_ different.  My environment is Solaris 7 and I'm using RRD 
1.0.25.  Here is what I get with the first example (the \'s are mine):

 > rrdtool create test.rrd --start 920804400 DS:speed:COUNTER:600:U:U \
    RRA:AVERAGE:0.5:1:24 RRA:AVERAGE:0.5:6:10
 > 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
 > rrdtool fetch test.rrd AVERAGE --start 920804400 --end 920809200
                     speed

  920804400: NaN
  920804700: NaN
  920805000: 4.0000000000e-02
  920805300: 2.0000000000e-02

  920807400: 2.0000000000e-02

  920808000: 1.3333333333e-02
  920808300: 1.6666666667e-02
  920808600: 6.6666666667e-03
  920808900: 3.3333333333e-03
  920809200: NaN

Am I making a simple mistake somewhere?  I've looked through the archives 
and couldn't find anything applicable.

Thanks,
Ron
