[rrd-users] problem with rrdrestore

[Kristoff Bonne]

Hi,


We have a strange problem with "rrdtool restore".


We are transfering mrtg / rrdtool statistics from one old server to a 
new one. The old server is a 32bit debian box. The new machine is 64 bit 
redhat.


Due to this migration from 32 to 64 bit, we need to use "rrdtool dump" 
to create a xml-file from the .rrd files on the 32bit machine and use 
"rrdtool restore" to convert them back to .rrd on the 64 bit box.


I have a .rrd file with gauge values between 0 and 10000. When 
converting it a value from the .rrd file to a XML file, I get values 
like (say) 6.534000000e+03 (so 6534).

However, when using "rrdtool restore" on the 64 bit box; this gets 
converted to just 6. I see that because a "rrdtool dump" of the 
resulting .rrd file on the 64 bit box returns (6.0000e+00).

I have that with all values in the .rrd file.




When only doing "rrdtool dump" and "rrdtool restore" on the 32bit box, 
it does work OK.


Is this a known issue? Anybody any ideas.
I'll start with compiling rrdtool from source on the 64bit box and see 
if this helps.



Chéééééééééééééério!
