从零件中提取一些字段 json 零件文本登录 Splunk

Question

我对 splunk 还很陌生，仍在学习。 我有一个 splunk 事件，它混合了一些文本和 json 介于两者之间。 （这不是完整的日志）

如何提取以下内容：

List of Applications in DQ to be marked "Obsolete in bapm": 
[487684fgfg, hfkeh708089, fgdh678, SDF75664, dffg0007643]
Total Application count from bapm ##1696
Total Application Asset in DQ ##1692
No of Application to Obsolete in DQ ##5

我尝试了类似下面的方法，在另一篇文章中针对类似情况提出了建议，但这不起作用：

index=hdt sourcetype=dq2 |  rex field=_raw "(?msi)(?<Total Application count from BAPM>\{.+\}$)"
| spath input="Total Application count from BAPM"

Answer 1

我的印象可能是错误的，您认为rex命令将同时搜索所有事件。 那不是下一个。 Splunk 单独且独立地处理每个事件。 查询必须准备好在任何事件中查找任何目标字符串。
