想要一起部署具有 3 个日志定义的 filebeat。发送到不同的输出目标。

logs1 的配置图

data:
  filebeat-logs1.yml: |-
    filebeat.inputs:
      - type: log
        enabled: true
        paths:
          - /var/log/logs1.json

    output.logstash:
      hosts: ["logstash-logs1.default.svc.cluster.local:5044"]

logs2 的配置图

data:
  filebeat-logs2.yml: |-
    filebeat.inputs:
      - type: log
        enabled: true
        paths:
          - /var/log/logs2.json

    output.logstash:
      hosts: ["logstash-logs2.default.svc.cluster.local:5044"]

logs3 的配置图

data:
  filebeat-logs3.yml: |-
    filebeat.inputs:
      - type: log
        enabled: true
        paths:
          - /var/log/logs3.json

    output.logstash:
      hosts: ["logstash-logs3.default.svc.cluster.local:5044"]

当每个日志文件发生变化时，每次只发送到第三个logs3的输出logstash-logs3.default.svc.cluster.local:5044。但是可以获取所有三个logs1.json/logs2.json/logs3.json文件的数据。

在这种情况下，filebeat 不能在一台机器上使用多个输出吗？

您可以有任意数量的输入，但只能有一个输出，您需要将日志发送到一个 logstash，然后您可以从那里将它们发送到其他地方。

Filebeat 不支持同时向多个 logstash 服务器发送相同的数据。为此，您必须使用不同的 logstash 服务器配置启动多个 Filebeat 实例。

这是 Filebeat 输出插件的限制

在同一主机上启动多个filebeat实例，可以参考这个链接
