[Orca-dev] Unordered data loading with multiple files for same day

[Guilherme Carvalho Chehab]

Hi there,

I am finishing some modifications on linux stats collector. 

One of the main alterations is the multiple file for a day, this will
resolve problems of losing graph data whenever there are changes of the
mount points, or NFS, and some reconfigurations that changes the number of
colums of Orca.

I have noted an issue that happens also with orcallator output files:
	- If you clean all rrds to force a new loading of the entire data
set, the find files sorting function (that is described on .cfg file) fails
to order correctly the array coorectly when there are multiple files in the
same day: e.g., percol-2002-10-10-000 or percol-2002-10-10-001. 
	- In consequence, when loadind the data, sometimes it gathers newer
data (-001 file) before the older one (-000 file). And due to the not read
older data limitation on RRD it ends creating holes on the graph.

I tried messing with the default sorting routine on orcallator.cfg to
reorder according with the sequence number, but had no success. Does anyone
found the same problem? 

I still believe that a simple change on the sorting algorithim is enough,
but the tries I made messed worsely... :-)

Any clues?

Regards,
Guilherme
