apache-kafka - Filebeat 5.0 输出到 Kafka 多个主题

Question

我在我的应用服务器上安装了 Filebeat 5.0 并且有 3 个 Filebeat 探矿者，每个探矿者都指向不同的日志路径并输出到一个名为 myapp_applog 的 kafka 主题。一切正常。

我的 Filebeat 输出配置到一个主题 - 工作

output.kafka:
    # initial brokers for reading cluster metadata
    hosts: ["broker.1.ip.address:9092", "broker.2.ip.address:9092", "broker.3.ip.address:9092"]

    # message topic selection + partitioning
    topic: 'myapp_applog'
    partition.round_robin:
      reachable_only: false

    required_acks: 1
    compression: gzip
    max_message_bytes: 1000000

我想要做的是根据条件将每个日志文件发送到单独的主题，请参阅 topics 上的文档部分.我曾尝试这样做，但没有向任何主题发送数据。有谁知道为什么我的条件不匹配或者它是正确的。我似乎可以找到有关如何正确使用“主题主题条件”的示例。

这是我的 kafka 输出到多个主题配置。

不工作

output.kafka:
    # initial brokers for reading cluster metadata
    hosts: ["broker.1.ip.address:9092", "broker.2.ip.address:9092", "broker.3.ip.address:9092"]

    # message topic selection + partitioning
    topics:
      - topic: 'myapp_applog'
        when: 
          equals:
            document_type: applog_myappapi
      - topic: 'myapp_applog_stats'
        when:
          equals:
            document_type: applog_myappapi_stats
      - topic: 'myapp_elblog'
        when:
          equals:
            document_type: elblog_myappapi
    partition.round_robin:
      reachable_only: false

    required_acks: 1
    compression: gzip
    max_message_bytes: 1000000

这是完整的 filebeat.yml 配置文件。

我遇到了同样的问题，并通过将输出定义为:

topics:
  - topic: '%{[type]}'
use_type: true

作为输入，您只需在 document_type: kaffka's topic 中设置

输入类型:日志
路径:

/路径/到/日志/文件
document_type: "你是卡夫卡的主题 1"

输入类型:日志
路径:

/path/to/another/log/file

document_type: "你是另一个卡夫卡的话题 1"
