On this site i found nice script to monitoring NBU:
exchange.nagios.org/directory/Pl ... me/details
but in my environment it's not working properly, in nagios /etc/local/nagios/libexec ./check_nrpe -H x.x.x.x -c check_nbu_backup -a $ARG1$
UNKNOWN: No handler for that command
In NSC.ini I wrote all settings. can anybody tell me what is wrong?
