Summary:

SELinux is preventing /usr/sbin/nagios "write" access on /var/spool/nagios/cmd.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by nagios. It is not expected that this access
is required by nagios and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Hash String generated from  catchall,nagios,nagios_t,nagios_spool_t,dir,write
audit2allow suggests:

#============= nagios_t ==============
#!!!! The source type 'nagios_t' can write to a 'dir' of the following types:
# nagios_log_t, nagios_tmp_t, var_run_t, var_log_t, nagios_var_run_t, tmp_t, root_t

allow nagios_t nagios_spool_t:dir { write add_name };
