benchmark question

[Fulton, David]

Do you have another box? I don't know of much of, if any, of an
advantage to running multiple instances. The SMP will usually not help
there because the other cores will be occupied executing plug-ins.  If
you had another box you could go with a distributed environment instead.
Perhaps using SVN to keep record of config changes.

List,
   Is there any information as to what is the maximum number of services
one can run on a single box with single instance of Nagios?  I did not
find any concrete data on this.

I am running a single instance of nagios on a quad core 2.5 GHZ machine
with with 4 Gigs of RAM.  

I have total of 7359 service check running on this box.  I have also
ndoutils running on the same box as backend.  

My total service checks is going to five fold very soon with a lot of
nrpe checks.  

Now, my question is should I run multiple instance of nagios on the same
box or a single instance will be able to handle about 30000 service
checks?

I already tested a dev environment with multiple instance of nagios with
some hacking to init.d script, it started and monitored fine.  What
would be the preferred method of running nagios, single instance on a
box or multiple instance on a box when we are dealing with high number
of service checks?   

Please comment on this.  Thanks
