[Orca-users] CPU used by orca itself !!

I believe that you're right about the rrd files being for long term data and
I'm sure I saw in the archive something about archiving the orcallator files
to reduce the orca workload looking for files.  
You could make an archive directory in each
.../var/orca/orcallator/<hostname> directory and move all but the latest
files into it.  That would keep orca from looking at them during each cycle.
Try it, you can always move them back.
If you don't need up-to-the-minute graphs all the time, then you could just
run orca every night and let it go through one time (use the -o option).

Thanks Leo.
I think I do have the same problem but I can't see how to prevent it.
I use an nfs share as my stoarge area for data from 3 machines. Each machine
writes to its own sub-directory on the nfs share and filenames are of the
orcallator-2004-11-15-000.bz2 , say. The current day's file is bzipped at
the end of the day and then left in there with all the other files. i.e
100 days we have 100 files.
Every 10 mins , when orca runs, it bunzips all 100 files and bzips them up
again !!! Surely this is not correct!? I thought the rrd files were there to
long term data.
Thanks anyone?

I had a similar experience because the method I used to transfer the orca
data to the system.  I initially used a simple scp via cron, but that
updated the mod time for the files and that caused orca to unzip, open and
reread every file.  

You might check to see if you have the same problem.

Hi all, 
I have just joined the list and would be happy to know 
how to get to any archives to see if my question has 
already been answered. 

If not ... 
I am very concerned about the amount of cpu consumed 
by orca itself. i.e. on the machine accumulating and processing 
the data into web-viewable format. I attach an example - orca's 
own graph - of the machine's CPU since orca was installed. 
This cpu is virtually ALL orca! It processes the data for itself and 2 
other machines. They are all SUN boxes with 2x10002MHz CPUs. 

Any comments v welcome.
