In the picture stacktrace of log message taking the new log line  
I want them in one log.  
How to do that ?

**Here is my log example :**

> 2020-10-01 16:39:18.4120 ERROR LeadsController bhavin [http://bhavin/Leads/New](http://bhavin/Leads/New) POST 192.168.43.244 Provide a valid PhoneNumber.GurukulERP.Logic.InvalidDataException: Provide a valid PhoneNumber.  
> at GurukulERP.API.Controllers.CRM.LeadsController.New(AdmissionLead model) in D:\Git\gbase.API\API\Controllers\CRM\LeadsController.cs:line 474

**here is my multiline pattern:**  
multiline.pattern: '\[1\]'  
multiline.negate: false  
multiline.match: after

* * *

1. [:space:]

Hi,

I guess the problem is that the first line of the stacktrace does not start with a space - it starts with a dash sign. There are multiple threads within this forum for multiline support (e.g. [Filebeat multiline regexp patterns help](https://discuss.elastic.co/t/filebeat-multiline-regexp-patterns-help/170648)). Please have a look there. In short:

- change the pattern to match your date-time at the start of the main line
- switch negate to true

Best regards  
Wolfram
