Amazon Linux AMIでNagiosを動かそうと思ったら、そのままではExternal Commandが動作しませんでした。

Error: Could not open command file '/var/spool/nagios/cmd/nagios.cmd' for update!

Summary    : Nagios monitors hosts and services and yells if somethings breaks

Description: Nagios is a program that will monitor hosts and services on your
           : network.  It has the ability to send email or page alerts when a
           : problem arises and when a problem is resolved.  Nagios is written
           : in C and is designed to run under Linux (and some other *NIX
           : variants) as a background process, intermittently running checks
           : on various services that you specify.
           : The actual service checks are performed by separate "plugin"
           : programs which return the status of the checks to Nagios. The
           : plugins are available at
           : http://sourceforge.net/projects/nagiosplug.
           : This package provides the core program, web interface, and
           : documentation files for Nagios. Development files are built as a
           : separate package.
