Request log emitter question

Hi,
I enabled request logs on one of my historical nodes by going through Druid docs - http://druid.io/docs/latest/configuration/index.html

druid.request.logging.type=emitter

druid.request.logging.feed=/logs/druid-historical/requests.log

in logs I see these:

2017-10-08T19:30:41,560 DEBUG [qtp257650296-144] io.druid.jetty.RequestLog - OPTIONS /status HTTP/1.0

2017-10-08T19:30:41,560 DEBUG [qtp257650296-143] io.druid.jetty.RequestLog - OPTIONS /status HTTP/1.0

2017-10-08T19:30:41,561 DEBUG [qtp257650296-146] io.druid.jetty.RequestLog - OPTIONS /status HTTP/1.0

2017-10-08T19:30:45,005 DEBUG [qtp257650296-145] io.druid.jetty.RequestLog - OPTIONS /status HTTP/1.0

2017-10-08T19:30:45,005 DEBUG [qtp257650296-147] io.druid.jetty.RequestLog - OPTIONS /status HTTP/1.0

but I don’t see any feed as configured in runtime.properties. Is there any other configuration required to see all queries hitting historical node? What am I missing?

Thanks,
