Filebeat不会将日志发送到logstash

所以这是大局： my objective is to index large amounts of (.txt) data using the ELK stack + filebeat.

基本上，我的问题是filebeat似乎无法将日志发送到logstash . 我的猜测是，一些docker网络配置已关闭...

我的项目代码可在https://github.com/mhyousefi/elk-docker获得 .

ELK CONTAINER

为此，我有一个 docker-compose.yml 从图像sebp/elk运行一个容器，如下所示：

version: '2'

services:
  elk:
    container_name: elk
    image: sebp/elk
    ports:
      - "5601:5601"
      - "9200:9200"
      - "5045:5044"
    volumes:
      - /path/to/volumed-folder:/logstash
    networks:
      - elk_net

networks:
  elk_net:
    driver: bridge

创建容器后，我转到容器bash终端并运行命令：

/opt/logstash/bin/logstash --path.data /tmp/logstash/data -f /logstash/config/filebeat-config.conf

运行此命令，我得到以下日志，然后它将开始等待而不打印任何进一步的日志：

$ /opt/logstash/bin/logstash --path.data /tmp/logstash/data -f /logstash/config/filebeat-config.conf

现在，这就是 filebeat-config.conf 的样子：

input {
  beats {
    port => "5044"
  }
}

output {
  elasticsearch {
    hosts => [ "localhost:9200" ]
    index => "%{[@metadata][beat]}"
  }
}

FILEBEAT CONTAINER

我的 filebeat 容器是使用bellow docker-compose.yml 文件创建的：

version: "2"

services:
  filebeat:
    container_name: filebeat
    hostname: filebeat
    image: docker.elastic.co/beats/filebeat:6.3.0
    user: root
    # command: ./filebeat -c /usr/share/filebeat-volume/config/filebeat.yml -E name=mybeat
    volumes:
      # "volumed-folder" lies under ${PROJECT_DIR}/filebeat or could be anywhere else you wish
      - /path/to/volumed-folder:/usr/share/filebeat/filebeat-volume:ro
    networks:
      - filebeat_net

networks:
  filebeat_net:
    external: true

创建容器后，我转到容器bash终端，将 /usr/share/filebeat 下的现有 filebeat.yml 替换为我已经使用的容器，然后运行命令：

./filebeat -e -c ./filebeat.yml -E name="mybeat"

终端立即显示以下日志：

root@filebeat filebeat]# ./filebeat -e -c ./filebeat.yml -E name="mybeat"

每隔30秒，它会显示以下内容：

并且在Kibana中没有创建索引模式 .

这就是我的 filebeat.yml 的样子：

filebeat.inputs:
- type: log
  paths:
    - /path/to/a/log/file

output.logstash:
  hosts: ["elk:5044"]

setup.kibana:
  host: "localhost:5601"

我使用this stackoverflow question来定义 docker-compose 文件的 networks 部分，以便我的容器可以使用 container_name 来相互通信 .

所以，当我这样做的时候

output.logstash:
  hosts: ["elk:5044"]

我希望filebeat将日志发送到elk容器的端口5044，其中logstash正在侦听传入消息 .

在我的终端内运行filebeat之后，我确实在终端中看到了以下日志： docker-compose up elk ：

elk    | 
elk    | ==> /var/log/elasticsearch/elasticsearch.log <==
elk    | [2018-08-14T11:51:16,974][INFO ][o.e.c.m.MetaDataIndexTemplateService] [fZr_LDR] adding template [logstash] for index patterns [logstash-*]

我假设logstash和filebeat之间已经进行了某种沟通 .

但是，另一方面，尽管遵循上面提到的stackoverflow响应，我不能在我的filebeat容器中执行 ping elk . 主机名未解析 .

我感谢任何帮助！

UPDATE (Aug 15, 2018)

我想我甚至不需要为我的 ELK 容器打开一个端口 . 会发生什么是 Logstash 正在侦听容器内的端口5044 . 只要 Filebeat 容器中的 filebeat.yml 文件可以解析 ELK 主机，然后将其日志发送到那里的5044端口（"elk:5044"），它们都应该可以正常工作 .

这就是为什么我删除了 "5045:5044" 行，并修复 docker-compose.yml 文件中 docker-compose.yml 文件的 networks 部分以包含以下内容：

networks:
  filebeat_net:
    external:
      name: elk_elk_net

它似乎有效，因为当我做 ping elk 时，我正在 Build 联系 .

While the networking issue is resolved (I can ping!), the connection between Logstash and Filebeat remains troublesome, and keep getting the following message every 30 seconds.

2018-08-14T12:13:46.334Z        INFO    [monitoring]    log/log.go:124  Non-zero metrics in the last 30s        {"monitoring": {"metrics": {"beat":{"cpu":{"system":{"ticks":20,"time":{"ms":24}},"total":{"ticks":30,"time":{"ms":36},"value":30},"user":{"ticks":10,"time":{"ms":12}}},"info":{"ephemeral_id":"16c484f0-0cf8-4c10-838d-b39755284af9","uptime":{"ms":30017}},"memstats":{"gc_next":4473924,"memory_alloc":3040104,"memory_total":3040104,"rss":21061632}},"filebeat":{"harvester":{"open_files":0,"running":0}},"libbeat":{"config":{"module":{"running":0}},"output":{"type":"logstash"},"pipeline":{"clients":1,"events":{"active":0}}},"registrar":{"states":{"current":0}},"system":{"cpu":{"cores":6},"load":{"1":1.46,"15":1.52,"5":1.66,"norm":{"1":0.2433,"15":0.2533,"5":0.2767}}}}}}

在我的filebeat容器的终端中，在详细模式下运行filebeat命令时，我也会定期收到以下日志：

    默认情况下，在容器中命名空间的网络连接，这意味着每个容器获取它自己的私有IP，容器中的localhost只是该容器的本地 .

    这意味着您需要在配置文件中指定弹性服务器的DNS条目，而不是localhost . 使用compose和swarm模式，服务名称将自动设置为指向容器的DNS条目：

    input {
  beats {
    port => "5044"
  }
}

output {
  elasticsearch {
    hosts => [ "elk:9200" ]
    index => "%{[@metadata][beat]}"
  }
}

    这还要求您在容器之间共享公共网络 . 在同一个撰写文件中创建所有内容时，默认情况下会得到此信息 . 当您部署了多个堆栈/项目时，您需要在至少一个文件中定义一个公共外部网络 . 由于我无法告诉您的elk项目名称知道完整的网络名称，因此以下是您可以对elk进行更改以将其连接到filebeat_net：

    version: '2'

services:
  elk:
    container_name: elk
    image: sebp/elk
    ports:
      - "5601:5601"
      - "9200:9200"
      - "5045:5044"
    volumes:
      - /path/to/volumed-folder:/logstash
    networks:
      - elk_net
      - filebeat_net

networks:
  elk_net:
    driver: bridge
  filebeat_net:

    我终于能够解决我的问题了 . 首先，如我的问题的 UPDATE (Aug 15, 2018) 部分所述，解决了容器连接问题 .

    Filebeat 没有将日志发送到 Logstash 的问题是由于我没有明确指定我的输入/输出配置被启用（这对我来说是一个令人沮丧的事实，因为它没有在文档中明确提到） . 因此，更改我的 filebeat.yml 文件以下修复了诀窍 .

    filebeat.inputs:
- type: log
  enabled: true
  paths:
    - ${PWD}/filebeat-volume/data/*.txt

output.logstash:
  enabled: true
  hosts: ["elk:5044"]
  index: "your cusotm index"

setup.kibana:
  host: "elk:5601"
