Unable to see NTP and SONAR logs in SEPM 12.1 console

Hi,

Recently, I have upgraded the SEPM console from 110.6 to SEP 12.1.2015.2015. Since after the upgrade, unable to see the logs for two components i.e. Network Threat protection and SONAR. For others components like Risk, Application contorl logs are present.

Before upgrading the SEPM console, it was working perfectly fine.

Clients are still running on 11.0.6

Anybody suggest what need to be checked
