Hi All  
new here and in general to Logs in general  
i have encountered problem to generate a Grok (for an extractor) pattern so it will capture string cut in the middle (sometimes) by a CR and continues, i want to capture it all to one variable (not containing the CR and spaces if exists)  
the string is  
2019-04-14 15:15:26 0x2b92f0e00700[A  
WS\_OSCAR\_INFO]:Taking preemptive lock on ''.bla bla bla'  
i want to capture the AWS\_OSCAR\_INFO as a parameter loglevel  
searched a lot , and tried myself but couldnot solve it  
the max is that i got parameter containg A WS\_OSCAR\_INFO , but i want it without the space  
thanks for the helpers...

Try

```
    grok { match => { "message" => "\[%{DATA:foo}\]" } }
    mutate { gsub => ["foo", "\s*", ""] }
```
