Splunk for F5 Networks LTM v11 iRule

Guys,i was able to send syslogs to splunk via the following. 1.Irule via HSL statements. 2."tmsh create sys syslog" -> Plain syslog server.

However when i try to set up HSL looging through log publishers,it is giving below logs in splunk. Basically we want to send /var/log/ltm logs to splunk using below solution article. https://support.f5.com/kb/en-us/products/big-ip-afm/manuals/product/dns-dos-firewall-implementations-11-6-0/13.html?sr=43696953 Error message:- Feb 06 16:39:55 default send string.
