LTM logs(All events) to splunk using HSL

the HSl configuration that i did is partially working. I have created a request logging profile and have modified the template in http request to fit the SIEM parser format and sequence and that works like a sweet candy using the tmm interface i configured and mapped the the new vlan.

Now the problem is the i am not getting the system logs via HSL. i cannot see any audit log. Incase i add the siem server as remote syslog server then i start receiving but i loose control as i cannot use my log filter because it is not using the hsl.

had raised a f5 case. there is something which is still not triggering the system logs through hsl tmm interface.
