Why Logstash is not pushing data to ES ?

Problem
Data not pushed by logstash (When we launch logstash using config file)

Possible issues
May be, Data already pushed to ES

Soluton

• Remove the logstash index created
• Launch logstash
• If problem still there
• Just add one line at the end of log file so that Logstash can pick the changes
• Launch logstash again
