Graylog 日志多行合并

多行合并

配置示例:

# Needed for Graylog
fields_under_root: true
fields.collector_node_id: ${sidecar.nodeName}
fields.gl2_source_collector: ${sidecar.nodeId}

output.logstash:
   hosts: ["10.0.107.111:5044"]
path:
  data: C:\Program Files\Graylog\sidecar\cache\filebeat\data #filebeat数据目录
  logs: C:\Program Files\Graylog\sidecar\logs  #sidecar日志目录
tags:
 - windows
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - F:\CODE\arrow-log\logs\*.log # 日志路径
  fields:
   app_name: example_glef_graylog
   environment: local
   log_type: Java
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}' # 匹配以时间格式为yyyy-MM-dd HH:mm:ss.SSS格式开头的日志
  multiline.negate: true 
  multiline.match: after

根据时间戳合并多行

  multiline.negate: true
  multiline.match: after

此配置使用negate: true和match: after设置来指定任何不符合指定模式的行都属于上一行。
