A daft move as I now have been charged with setting up a system for evaluation. I have configured most of the systems ok and have nrpe working however I am having some issues with the check_log plugin, it is now reporting Status Information: Log check error: Log file -O does not exist! It was working, so I am pretty confused! The definition on the client nrpe.cfg is #Matts check_log definition command[check_log]=/usr/lib/nagios/plugins/check_log -F $ARG1$ -O $ARG2$ -q $ARG3$ and at the server end # check_log command definition define command{ command_name check_log command_line $USER1$/check_log -F /var/log/messages -O /var/tmp/check_log_messages -q "yum" } When run on the command line it works fine. Can anyone shed any light on this or suggest where to look?
