Hello,

i would like to retrieve only the name of my log file, but my grok filter doesn't work. When i put it in grok debugger it works without any problems, also logstash doesn't report any error, i just get tag grokparsefailure .

```auto
filter {
    grok {
# break_on_match => false
# match => { "message" => "%{SYSLOG5424SD:logtimestamp} %{GREEDYDATA:errorlog}" }
        match => { "path" => "%{URIPATH}/channel-%{WORD:channel}.log" }

    }
  }

```

My path is (copied from elasticsearch):  
log.file.path /var/logs/channel-SMTH.log

I want my result to be only:  
{  
"channel": "SMTH"  
}

Anyone have any idea what i did wrong?

You would need to do the match to "[log][file][path]", not just "path".
