title: flume : find ip/hostname of event sender?
body: <p>I am trying to setup data pipeline where applications servers send (using log4j logging) logevents to flume (using flume log4j appender) over network , to a avrosource that flume agent is using </p>
  
  <p>I tried with below configration but It only appends IP of the host on which agent is running </p>
  
  <p><code>A1.sources.logE.interceptors = hostint
   A1.sources.logE.interceptors.hostint.type =         org.apache.flume.interceptor.HostInterceptor$Builder
   A1.sources.logE.interceptors.hostint.preserveExisting = true
   A11.sources.logE.interceptors.hostint.useIP = false</code></p>
