解码 XML Wineventlog
编辑解码 XML Wineventlog
编辑此功能处于技术预览阶段,可能会在将来的版本中更改或删除。Elastic 将努力解决任何问题,但技术预览中的功能不受官方 GA 功能的支持 SLA 的约束。
decode_xml_wineventlog
处理器解码存储在field
键下的XML格式的Windows事件日志数据。它将结果输出到target_field
。
输出字段将与winlogbeat winlog 字段相同。
支持的配置选项如下:
-
field
- (必填) 包含 XML 的源字段。默认为
message
。 -
target_field
- (必填) 将解码的 XML 写入到的字段。要将解码的 XML 字段合并到事件的根目录,请使用空字符串指定
target_field
(target_field: ""
)。默认值为winlog
。 -
overwrite_keys
- (可选) 一个布尔值,指定事件中已存在的键是否会被解码的 XML 对象中的键覆盖。默认值为
true
。 -
map_ecs_fields
- (可选) 一个布尔值,指定是否尽可能映射额外的 ECS 字段。请注意,ECS 字段键位于
target_field
之外。默认值为true
。 -
ignore_missing
- (可选) 如果为
true
,则当指定字段不存在时,处理器不会返回错误。默认为false
。 -
ignore_failure
- (可选) 忽略处理器产生的所有错误。默认为
false
。
