Hello every one  
I need to access to my filename date.  
this is the filter i wrote in my logstash

```auto
filter {
    grok {
        match => { "path" => ["^%{GREEDYDATA}(?<year>[0-9]{4})(?<month>[0-9]{2})(?<day>[0-9]{2})(?<hour>[0-9]{4})%{GREEDYDATA}" ] }
      }
}

```

and this is the output of my file path "path" =\> "/etc/logstash/conf.d/myfile/202005020759.txt"  
but nothing appear to my logstash output as a field of year month and day..even i tried this:

```auto
filter {
    grok {
        match => { "path" => ["%{GREEDYDATA:some}"] }
      }
}

```

but still no out put in my logstash.

What does your raw incoming message look like and what is the output you are using?
