Description of problem:

SELinux is preventing /usr/sbin/collectd from create access on the netlink_tcpdiag_socket .

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

If you believe that collectd should be allowed create access on the  netlink_tcpdiag_socket 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 collectd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
