配置Logstash以从socket接收数据，并将其插入java中的Elasticsearch

Question

我想将数据直接注入ElasticSearch以执行一些性能测试。我的第一个想法是为每个文档创建JSON文件，并将这些文件导入ElasticSearch，但这会花费太长时间。我测试了110K个文件，创建这些文件只花了18分钟，我需要5500万个文档——这是我测试的500倍。快速计算：需要150小时，或者6.25天，太长了。 第二个选项是在stirng中包含JSON并使用Logstash将字符串注入ElasticSearch时停止。但是，我有一个例外：

2019-12-16 13:49:27,240 | Timer-0 | ERROR | search-injector | c.n.es.injector.output.SocketOutput | SocketOutput::output: 
java.net.SocketException: Software caused connection abort: socket write error

ElasticSearch在localhost端口9200上运行，Logstash在localhost端口9600上运行。 我的袜子发出来了。爪哇

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;

import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;

public class SocketOutput implements OutputHandler {

    private static final Logger log = LoggerFactory.getLogger(SocketOutput.class);

    public static final String CLI_OPTION = "socket";

    @Value("${socket.hostname}")
    private String hostname;
    @Value("${socket.port}")
    private int port;
    Socket clientSocket;

    public boolean open() {
        try {
            clientSocket = new Socket(hostname, port);
        } catch (IOException ioe) {
            log.error("", ioe);
            return false;
        }
        return true;
    }

    @Override
    public void output(String data) {

        DataOutputStream outToServer = null;
        try {
            outToServer = new DataOutputStream(clientSocket.getOutputStream());
            outToServer.writeBytes( data );
        } catch (IOException ioe) {
            log.error("", ioe);
        }
    }

}

logstash很简单。形态

# Simple Logstash configuration for creating a simple
# Stdin -> Logstash -> Elasticsearch pipeline.
input { stdin { } }

output {
  elasticsearch { 
    hosts => ["http://localhost:9200"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
  }
  stdout { codec => rubydebug }
}

我正在使用以下命令运行Logstash：bin/logstash.bat -f config/logstash-simple.conf

JSON字符串已创建且有效，Socket将获得正确的参数值（hostname=“localhost”和port=9600）。 我将感谢任何帮助

解决方案有几个层次，首先使用Kibana管理器在Elastic Search中创建并使用正确的索引，然后正确配置Logstash，最后使用JSON字符串而不是文件

创建索引不是这个问题的问题，所以我不会深入讨论

Logstash。配置文件：

#################################################
# Stdin -> Logstash -> Elastic Search pipeline.
#################################################
input {
    stdin{}
    tcp{
        host => "localhost"
        port => 9600
        codec => json
    }
}

filter 
{
   mutate 
    {
        remove_field => ["host", "@version", "@timestamp", "port", "tags", "level", "logger_name", "themessage", "mensage", "spring.application.name", "level_value", "thread_name"]
    }
}

output {
    stdout{ codec => rubydebug }

     elasticsearch{
        hosts => ["localhost:9200"]
        index => ["my-index"]
     }
}

注意：在index中输入您创建并将使用的索引的名称

正在使用配置文件运行Logstash：bin/logstash.bat -f config/logstash-simple.conf

将字符串输出到Java中的Logstash：

package com.beniregev.injector.output;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;

import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;

public class SocketOutput implements OutputHandler {

    private static final Logger log = LoggerFactory.getLogger(SocketOutput.class);

    public static final String CLI_OPTION = "socket";
    private int outputIndex = 0;

    @Value("${socket.hostname}")
    private String hostname;
    @Value("${socket.port}")
    private int port;
    Socket clientSocket;

    public boolean open() {
        try {
            clientSocket = new Socket(hostname, port);
        } catch (IOException ioe) {
            log.error("", ioe);
            return false;
        }
        return true;
    }

    @Override
    public void output(String data) {
        DataOutputStream outToServer = null;
        try {
            outToServer = new DataOutputStream(clientSocket.getOutputStream());
            outToServer.writeBytes( data );
            outputIndex++;
        } catch (IOException ioe) {
            log.error("", ioe);
        }
        System.out.println("Wrote segment " + outputIndex + " to socket");

    }

}

host和port是到Logstash，默认端口为9600

这为我解决了问题
