First make sure this is all the access that it needs by running logwatch
with setenforce 0.
Then send us the AVC messages, so we can update policy.
I run today my system in permissive mode and logwatch showed disk usage
of all partitions mounted in /mnt. Here are AVC messages:

(Yes, I don't have auditd.)
You can also install a loadable module to allow this access by executing
grep logwatch /var/log/audit/audit.log | audit2allow -M logwatch
semodule -i logwatch.pp
I know about audit2allow, but this program sometimes allows to much. I
wanted to ask about this issue developers of SELinux policy :)
Thanks,
Dawid
