How to hide Job Server log entires

Hi All,

        I have configured job servers to show only WARNING messages.  Now log files are capturing following messages only while running AD sync job:

x><s>2014-01-23 10:07:28 -06:00 - VI.JobService.JobComponents.SQLComponent - f074ffe4-46c0-4bcf-8e3b-1c78f3a93ca6: Successful

<x><s>2014-01-23 10:08:58 -06:00 - VI.JobService.JobComponents.ScriptComponent - d1e28d3e-0e26-4a4d-9abb-004db03c6556: Successful

Currently we have more than 100K users in AD, log files are filled with SQL Component and ScriptComponent messages.  How can we ignore these messages into Job Server Log file?

thanks
