F22 rsyslogd writes to a dated file name...

[dwoody5654]

The following is a current list of the messages file in /var/log:

-rw-------. 1 root root 104339300 Jun 20 10:27 messages-20150614
-rw-------  1 root root                 0 Jun 22 03:30 messages
-rw-------  1 root root  36077670 Jun 25 20:25 messages-20150622

The other log files are treated similarly.

-rw-------. 1 root root 9446999 Jun 20 10:27 secure-20150614
-rw-------  1 root root             0 Jun 22 03:30 secure
-rw-------  1 root root 1493733 Jun 25 20:38 secure-20150622

I have bot been able to find out why the messages file is zero length or 
why the messages file that is being written to is a date identified 
file, in this case messages-20150622.

Is there a config setting to change this?
