Dependency and performance question

[shadih rahman]

Hi,
   I am running nagios on a 2.5 GHZ 4-core 64 bit machine running RHEL5.  I
am seeing some performance issue in Nagios.  I am doing failover setup.  I
have another similar machine which has identical config but not doing any
active checks.  My master machine sends check result using NSCA.  Now I can
not determine why my master machine is lacking in performace.  I will paste
my performance data below.  I also have another question about dependency.

1) if a HOST is down, does the service checks still happens?  I would like
to setup a dependency where if host is down no service check should take
place.  How do I go about setting this up.  An exapmple will be much
appreciated.

2) How can I start troubleshooting my performance issue?

Thanks in advance.
