You should be able to do this.  However, make sure to strip out all 
references to program starts/stops/restarts in the distributed logs 
before you merge them into the central log.  

Also, if you do this you will probably have some slight inaccuracies 
with regards to availability reports on the distributed 
hosts/services.  The main reason for that is that the central and 
distributed copies of Nagios probably started/stopped/restarted at 
different times and Nagios logs some events (like initial state info) 
immediately after startup.  I don't think this should affect things 
negatively too much, but keep the original logs around just in case 
the combined log gives you problems.
