Hello everyone

I am a beginner in logstash filter and to better understand the patterns I wanted to put a pattern to add the processing time of requests (in millisencodes) in my logs.

The problem is that I can't find any pattern that looks roughly what I want  
Do you have any suggestions for a start

Attached is the logstash conf that I currently have

Thank you

#logstash filter

filter {  
if [type] == "apachecvs"{  
grok { match =\> { "message" =\> "%{IPORHOST:clientip} %{USER:ident} %{USER:auth} [%{HTTPDATE:logdate}] "(?:%{WORD:verb} %{NOTSPACE:request}(?: HTTP/%{NUMBER:httpversion})?|%{DATA:rawrequest})" %{NUMBER:response} (?:%{NUMBER:bytes}|-)" }  
}  
date {  
match =\> ["logdate", "dd/MMM/YYYY:HH:mm:ss Z"]  
timezone =\> "Europe/Paris"  
target =\> "logdate"  
}  
}  
}
