Hi Robert,
Have you enabled the log option after that acl, if yes, than use the following option after the acl,
access-list out_in permit ip any any log interval 1
and then check again, some delay is expected because, in case of the ASDM log viewer, the java application fetches the data from the ASA,but in a syslog server the ASA sends the data to the syslog.
Hope this helps
Thanks,
Varun
