Hi Verma1729,
To my knowledge there is released add-on/app for ingesting the Trend Micro Control Manager Logs.
We had the same issues and ended up configuring DB connect to pull the logs directly from the Control Manager database then build it out from there.
The Control manager DB schema is not publicly available so you will need to contact your TAM to get your hands on it.
Link to DB Connect: https://splunkbase.splunk.com/app/2686/
Cheers,
Matt
