Error in reactor loop escaped: closed stream (IOError)

I am trying to setup logstash in my system, below are the steps I followed

  1. Downloaded the zip file logstash-7.12.0-windows-x86_64.zip from the official website Download Logstash free

  1. Unzipped and executed this command bin/logstash.bat -f logstash-sample.conf --log.level debug

  2. Logstash started the API successfully, but it got shutdown and showing the below error
    Error in reactor loop escaped: closed stream (IOError)

  3. logstash-sample.conf file

input { stdin { } }
output {
  elasticsearch { hosts => ["localhost:9200"] }
  stdout { codec => rubydebug }
}

see the log

Solution

  • This error usually occurs when the conf file specified is not a valid file or path. Check the entire log to see if there is an error "No configuration found in the configured sources". If the file is under the logstash conf folder then execute the following command from the root folder in windows

    bin\logstash -f config\logstash-sample.conf
