I have following pattern file.  
CPAT ([\w-]+)  
FRDOM ([\w-]+)  
DEVC ([\w]+)

I had given permission for pattern file. but it gives the following error.

Pipeline aborted due to error {:exception=\>#\<Grok::PatternError: pattern %{CPAT:devicename} not defined\>

my filter is like this.  
grok{  
patterns\_dir =\> ["/etc/logstash/pattern.d"]  
match =\> { "message" =\> "%{CISCOTIMESTAMP:timestamp} %{IP:serverip}.%%{DEVC:dev}.%{DEVC:devnum}.%{DEVC:status}: Device('%{CPAT:devicename}'/'%{CPAT:device}'/%{CPAT:devicemac}. at %{FRDOM:dom}.'%{FRDOM:rfdomain}" }  
}

In 6.2.4, with that filter (provided you add a backslash between Device and the parenthesis) I do not get an error. Can you re-post the match line from the grok filter with 4 leading spaces like this:

```
match => { "message" => "%{CISCOTIMESTAMP:timestamp} %{IP:serverip}.%%{DEVC:dev}.%{DEVC:devnum}.%{DEVC:status}: Device\('%{CPAT:devicename}'/'%{CPAT:device}'/%{CPAT:devicemac}. at %{FRDOM:dom}.'%{FRDOM:rfdomain}" }

```

BTW, do you really want %% before the first DEVC?
