oh I'm sorry it is my own problem I don't have pointed to filebeat logstash, logstash listening on port 5044 But have not received any data.May be because of this error.I modified filebeat configuration file and point to logstash after problem solved.I am logstash version 2.1.1.

Logstash - input - beats plug-in seems to be installed by [default.By](http://default.By) way of RPM.
