Hi All,

We are facing issue while logstash startup. We are trying with Sun JDK 7 and 8. Are there any additional steps required for startup ? We are using logstash 1.5.2 and 1.5.4 and 2.0.

Are there any additional steps required during the installation ?

Please help.

Regards

What OS are you on?

Can you share your config?

I have installed logstash on Cent-OS 6.6. Sun Java 1.7.

```
input {
  file {
    path => ["/var/log/varnish/varnish-access*.log"]
      type => "varnish"
      start_position => "end"
      stat_interval => 3600
  }
}

filter {
  if [type] == "varnish" {
    grok {
      match => ["message", "\[%{HTTPDATE:request_date}\] \"%{WORD} %{URI:request_url} HTTP/%{NUMBER:httpversion}\" %{NUMBER:response_code:int} %{NUMBER:response_time:int}"]
    }
  }

    
  date {
    match => ["request_date" , "dd/MMM/yyyy:HH:mm:ss Z"]
  }

  mutate
  {
    remove_field => ["request_date"]
  }

}

output {
  elasticsearch_http { host => "test01" }
  stdout {
    codec => rubydebug
  }
}
```
