[rrd-users] Graphing on embedded arm system

[Ron Jobmann]

Hi Fernando
I created the same database separately on each machine.  One interesting aspect of that is slightly different data as revealed by
Fetch.

x86:
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

ARM:
920804700: nan
 920805000: nan
 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

This shouldn't be the cause of the screwed up graph though.

I have the same libraries available on each machine.  libpng12, libz, libm.  If I use the unix 'strings' command on the rrdtool binaries,
the same libraries show up for each.  It seems like I'm still missing something on the ARM board.

To move the database you need to export the data on the arm platform and then import them on the PC platform, simply copying the files doesn't work probably due to the different "endianess" of he 2 platforms.

Hope this helps.
