commit 4c8ca4f51e39ad099a8e52157acfc38ad811fab7
Author: Hari Prasad Killi <email address hidden>
Date: Sat May 27 10:08:12 2017 +0530

Initialize all variables in Agent Param.

As log file count is not initialized, it takes random value and is
causing Agent hogging CPU whenever log file rotation is required

Also initialized other missing variables.
