Невозможно просматривать новые журналы в режиме реального времени при весенней загрузке с установкой ELK

Это настройка:

Я запускаю ELK локально с приложением весенней загрузки java, которое записывает журналы в файл с именем elk-logs.log

Я могу чтобы увидеть журналы в кибане при первом запуске приложения java spring boot, но после начальной загрузки приложения я не могу видеть новые журналы впоследствии. Журналы - это , записываемые в файл журнала (называемый elk-logs.log) в реальном времени, но я считаю, что logsta sh не читает их должным образом.

logsta sh .conf: 

input {
  file {
    type => "java"
    path => "/Users/coinflex/sandbox/elk-demo/elk-logs.log"
    codec => multiline {
      pattern => "^%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{TIME}.*"
      negate => "true"
      what => "previous"
    }
  }
}

filter {
  #If log line contains tab character followed by 'at' then we will tag that entry as stacktrace
  if [message] =~ "\tat" {
    grok {
      match => ["message", "^(\tat)"]
      add_tag => ["stacktrace"]
    }
  }

 grok {
    match => [ "message", 
               "(?<timestamp>%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{TIME})  %{LOGLEVEL:level} %{NUMBER:pid} --- \[(?<thread>[A-Za-z0-9-]+)\] [A-Za-z0-9.]*\.(?<class>[A-Za-z0-9#_]+)\s*:\s+(?<logmessage>.*)",
               "message",
               "(?<timestamp>%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{TIME})  %{LOGLEVEL:level} %{NUMBER:pid} --- .+? :\s+(?<logmessage>.*)"
             ]
  }


  date {
    match => [ "timestamp" , "yyyy-MM-dd HH:mm:ss.SSS" ]
  }
}

output {

  stdout {
    codec => rubydebug
  }

Приложение Spring Boot действительно простое. Просто основной класс ELkDemoApplication и класс ElkController с некоторым маршрутом, который я использую для запуска регистратора после посещения localhost: 8080 /

ElkDemoApplication. java: 

package com.elk.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;

@SpringBootApplication (exclude = SecurityAutoConfiguration.class)
public class ElkDemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(ElkDemoApplication.class, args);
    }

}

ElkController. java: 

package com.elk.demo.controller;

import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.Date;

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.core.ParameterizedTypeReference;
import org.springframework.http.HttpMethod;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;


@RestController
class ELKController {
    private static final Logger LOG = Logger.getLogger(ELKController.class.getName());


    @Autowired
    RestTemplate restTemplete;

    @Bean
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @RequestMapping(value = "/elkdemo")
    public String helloWorld() {
        String response = "Hello user ! " + new Date();
        LOG.log(Level.INFO, "/elkdemo - &gt; " + response);

        return response;
    }

    @RequestMapping(value = "/elk")
    public String helloWorld1() {
        String response = restTemplete.exchange("http://localhost:8080/elkdemo", HttpMethod.GET, null, new ParameterizedTypeReference<String>() {
        }).getBody();
        LOG.log(Level.INFO, "/elk - &gt; " + response);

        try {
            String exceptionrsp = restTemplete.exchange("http://localhost:8080/exception", HttpMethod.GET, null, new ParameterizedTypeReference<String>() {
            }).getBody();
            LOG.log(Level.INFO, "/elk trying to print exception - &gt; " + exceptionrsp);
            response = response + " === " + exceptionrsp;
        } catch (Exception e) {
            // exception should not reach here. Really bad practice :)
        }

        return response;
    }

    @RequestMapping(value = "/exception")
    public String exception() {
        String rsp = "";
        try {
            int i = 1 / 0;
            // should get exception
        } catch (Exception e) {
            e.printStackTrace();
            LOG.error(e);

            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw);
            e.printStackTrace(pw);
            String sStackTrace = sw.toString(); // stack trace as a string
            LOG.error("Exception As String :: - &gt; "+sStackTrace);

            rsp = sStackTrace;
        }

        return rsp;
    }
