I have issues with Multiline stack traces (.net) with whitespace. logs are getting split and we are not able to troubleshoot the things its more time consuming.

I tried the fix from ES-stack website

> **[Manage multiline messages | Filebeat Reference \[7.9\] | Elastic](https://www.elastic.co/guide/en/beats/filebeat/current/multiline-examples.html)**

but after applying the changes we are still getting the split logs with whitespace.

```

I guess not only whitespace would help here i need to combine it with below things:

- whitespace
- keyword "at"
- keyword/special-character "---"

Probably this would be on the basis of pattren i have observed above.
