I wanted to know if it is possible to pattern match the path of the files coming in from file beat in log stash? I am trying to extract the path but it did not work.

I tried something like this

input {  
beats {  
port =\> 5044  
}  
}

filter {  
grok {  
match =\> {  
"path" =\> "%{GREEDYDATA}%{SYSTEM:system}\_%{LOG:log}%{GREEDYDATA}"  
}  
}  
}

SYSTEM is not a built-in pattern. What does the field look like and which parts of it do you want to extract?
