Hi Jonathan,
Why not use check_by_ssh instead?
Is there any pitfall (weakness) in using check_by_ssh compared agent like OCP?
Thanks
Sam

Sean;
I have a very large deployment so I use this tool:
http://www.nagioscommunity.org/wiki/index.php/OCP_Daemon
This daemon runs on each of the distributed servers while a normal ncsa
daemon listens on the central server.

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.

Hello,
I have 1 central nagios system with 5 distributed servers. I have
enabled freshness checking on both central and remote systems. I am
constantly seeing services go to unknown status for 1-3 minutes and
then recover.
on the remotes I have:
check_service_freshness=1
service_freshness_check_interval=10
check_host_freshness=1
host_freshness_check_interval=60
service_inter_check_delay_method=s
max_service_check_spread=10
service_interleave_factor=1
host_inter_check_delay_method=s
max_host_check_spread=30
max_concurrent_checks=0
It does appear as though checks are being run in parallel. I'm
wonder
how I can best determine where the problem is, with the execution of
checks, submittal to the central system or other.
Thanks.
