How do i add custom field based on filebeat input 's glob path?

Hello,

I have a requirement , where i need to derive values based on the input path

example - i have a log file on a partition

format - /app/shared/1.1.1.1_webserver_ticket#1.log

From the above path , i need to extract the IP (1.1.1.1), component (webserver) and ticket (ticket#1) . My filebeat.yml looks like this


  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    - /app/shared/*webserver_comp1.log
    - /app/shared/*webserver_comp2.log

Now the logstash config is written to fetch these details via grok

filter {
  grok {
    match => { "path" => "%{IP:machineip}_%{NOTSPACE:component}_%{NOTSPACE:ticket}" }
  }
}

How do i add a field based on the input glob pattern on filebeats' input section and pass it along to logstash ? Should i use the processor ? would that work based on each glob pattern ?
