Description of problem:
Munin selinux read policy wrong for /etc/munin/plugins/open_files

occurs at the same time as:
https://bugzilla.redhat.com/show_bug.cgi?id=916686
SELinux is preventing /usr/bin/bash from 'read' accesses on the file file-nr.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that bash should be allowed read access on the file-nr file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep open_files /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
