Distributed monitoring Freshness checking failing then recovering

[Sean McAvoy]

On further investigations it looks as though the problem is with the  
time taken to submit the results back to nagios via send_nsca.
I have read about a couple different options for getting results back  
quickly. One being a bulk system of transfer, a file containing the  
results is sent via a send_nsca bulk transfer executed via cron. The  
other being a system that makes use of the performance data output  
option on the remote nagios systems and submits the results using a  
custom daemon on both ends.
Does anybody know of any other options? Also, is there any guides to  
setting up either of these options, most of what I have read is email  
threads..
Thanks.
