title: What is the best middleware for the following architecture ? (Logs, ELK, Tableau)
body: <p>Please guys, can anyone propose a clear concept about the best middleware choice for this architecture, I'm in need to a <b>real time</b> middleware which can be very rich in its inputs, filters and must be capable to <b>directly</b> reach  Tableau software as output?
  I'm lost between Logstash, Apache flume and their confusing output toward Tableau...</p>
  
  <p>If someone has another concept, I'm all ears !
  Thank you
