Filebeat 多行过滤器不起作用？

Question

我正在尝试从 filebeat 读取文件并将它们推送到 logstash。在推送它们之前，我试图合并包含 java 堆栈跟踪的事件。我试过这个过滤器，但没有用。

filebeat.prospectors:
- type: log
  paths:
- /mnt/logs/myapp/*.log

multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
multiline.negate: true
multiline.match: after

这是我尝试推送到 logstash 的日志示例。我想将堆栈跟踪事件合并到时间戳在它之前的事件中

合并事件后，如果我是对的，我想消息属性应该将两个事件消息连接起来，请帮助解决这个问题。

你的正则表达式应该不错。请参阅 https://www.elastic.co/guide/en/beats/filebeat/7.5/_test_your_regexp_pattern_for_multiline.html 如何实际测试它。
这可能只是复制粘贴错误，但您的 YAML 文件的缩进看起来不正确。还要检查您的 Filebeat 日志是否有错误。这应该是：
```
 - type: log
   paths:
     - /mnt/logs/*.log
   multiline:
     pattern: '^\['
     negate: true
     match: after
```
