yet resources.cfg contains the line, $USER1$=/usr/lib64/nagios/plugins
and the plugin files are all -rwxr-xr-x and owned root:root like on other working Icinga machines.
SELinux is disabled.
The /var/log/secure contains lines I don't understand.

EDIT: I can fix this permission issue by adding rules to /etc/sudoers allowing icinga to run these nagios binaries and editing my commands.cfg file to run sudo before the command, ex.
define command {
command_name check-host-icmp
command_line /usr/bin/sudo $USER1$/check_icmp -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
}
but that leads me to wonder if there isn't a cleaner way. Or why do the Nagios plugins need to be owned by root:root?
