Description of problem:
running smartctl from snmpd
SELinux is preventing /usr/sbin/smartctl from using the 'sys_rawio' capabilities.

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

If you believe that smartctl should have the sys_rawio capability 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 smartctl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
