[Orca-users] Orca using over 40% CPU on Server

[Garrett, Matt M SITI-ITDIEEE]

Folks

I have been running Orca Version 0.27 for over 6 moths now.
It does produce very good detail and superb graphs

However running on a Sun Solaris 8 system , Ultra 30 , UltraSPARC-II 296MHz CPU , 512Mb memory
The Orca process seems to all ways use over 40% of the CPU
The only reason it does not use 100% is other monitoring process (Nagios) need to run as well.

At the moment I am only monitoring 53 clients.
This is about to be stepped up to 300 clients.

Is the CPU going to go through the roof and grind the poor monitoring server to a halt !

The Orcas config file for base looks like
base_dir                /local/data1/orcallator_column_data

With all clients writing to the above via NFS , Note this is a local disk to the server , NFS mounted to the clients

I had thought of getting Orca just to generate the RRD files and then once a day getting it to generate the images / html files
but this kind of take's away the usefulness of nearline reports, and not sure if it would make any real difference.

Any suggestions or idea's would be very helpful

Thanks

Matt
