[Orca-users] Orca and Large Systems

[Mark Goldenberg]

I just finished installing Orca into a new production environment.  The 
environment is made up of 30+ systems range from Sun Fire 15000 to 
Netra T1 105's.  I have an HDS 9960 attached to the Sun Fire 15000 and 
Sun Fire 4800 with over 200+ LUNs.  I'm running Orca on a dual 750MHz 
Sun Fire 280R.

The 280R is constantly running a 43% User CPU usage after installing 
Orca.  I have the orcallator.se script set to collect data every 
600secs on each system.  And I'm using an rsync script to move the 
collected data to the 280R every 5mins.  Orca's HTML pages are running 
between 10-12mins behind.

The heavy load appears to be Orca processing the disk information from 
two SF15k domains and a SF4800.  When you have this many disk devices 
I'm not sure how useful the graphs are.  Can I simply comment out the 
disk sections of the orcallator.cfg file to shutdown this processing?  
Or can I turn it off on a system by system basis by editing the 
orcallator.se script?  Does anyone on this list have any suggestions?  
I would like to keep Orca as real time as I possible.  I'm currently 
trying to use the Orca output to assist with troubleshooting 
performance problems with a new project.
