Each submits all check results to each master in series -- $ tail -3 submit_check_result /bin/echo -e "$1\t$2\t$return_code\t$4\n" | /usr/local/nagios/bin/send_nsca master1 -p 5668 -c /usr/local/nagios/etc/send_nsca.cfg /bin/echo -e "$1\t$2\t$return_code\t$4\n" | /usr/local/nagios/bin/send_nsca master2 -p 5668 -c /usr/local/nagios/etc/send_nsca.cfg /bin/echo -e "$1\t$2\t$return_code\t$4\n" | /usr/local/nagios/bin/send_nsca master3 -p 5669 -c /usr/local/nagios/etc/send_nsca.cfg I've never seen failures and all checks are current on my masters. > An install I'm testing at the moment has around 4000 services on 3 minute > check split between an active master and a single slave (i.e. master > performing half the checks actively) Of the 2000ish distributed services, > I see anything up to 10 failed passive submits per hour with NSCA running > as a daemon on the master.
